Chakka-Chhh: The Hidden History of View-Master

Had it not been for the FBI informant working at Chase Bank, William Gruber might have been able to enjoy his success.

It was 1939, and the German immigrant’s chance meeting with an employee of Sawyer’s postcard company in Portland, Oregon had recently netted an important business deal: Sawyer’s was interested in mass-producing Gruber’s View-Master, a portable stereo photography viewer that used a separate image for each eye to create a 3D effect. Held up to a light source, the reels created an immersive still picture.

There was just one stumbling block: The lenses for the viewer were proving hard to source. Eager to help, Gruber recommended Sawyer’s use a German optical firm, which could produce the number needed at a reasonable 7.5 cents per lens. But by the time the deal was completed, trade embargoes had made doing business with Germany impossible. The firm refunded payment directly to Gruber, who then cut a check to Sawyer’s.

A German-born citizen being sent funds from Nazi-occupied Germany raised a flag at Chase; the FBI was notified by their informant at the branch, and Gruber was cornered for an explanation.

He had one. It was legitimate. But there was also no denying that Gruber was a Nazi sympathizer who had voiced his support of Hitler ever since he had arrived in Portland in 1924. Shortly after the View-Master debuted at the 1939 New York World’s Fair, Gruber was remanded to Idaho, where his assets were frozen and he faced charges of espionage. It was not a pretty picture.

Stereoscopes, using pictures cards known as stereographs, had been a popular parlor entertainment since the 19th century, when the 3D viewers were set up in common rooms. Growing up in Munich in the early 1900s, Gruber was fascinated with the devices and with photography in general.

It was a nice hobby, but hardly a proper career; Gruber’s family expected him to follow in his father’s trade as a blacksmith.

The food rationing that came as a result of the first World War dampened those plans. Malnourished, Gruber didn’t possess the physical strength to perform that kind of manual labor. Instead, he became a piano tuner, and moved to Oregon in 1924 to pursue American citizenship and explore his photography in a more scenic environment.

The relocation didn’t dilute his feelings about the Nazi party. Having joined in 1921, Gruber continued to believe Adolf Hitler could unite a divided Germany. Pro-German groups in Portland counted him among their members; he espoused pro-Hitler views to customers while tuning their pianos. It’s unlikely Gruber had any idea how his vocal support put him on the FBI’s radar.

In 1938, Gruber married a Portland native, Norma, and the two went on a honeymoon to a lodge near the Oregon Caves. While toting around his dual-camera tripod to snap stereoscopic images, Gruber ran into another photographer, Harold Graves, who had been dispatched to take photos of deer for Sawyer’s.

Graves was intrigued by the curious set-up; Gruber explained how he planned on a viewer that could display 3D images in color, preferably for educational purposes. In addition to national parks and famous cities, the slides could provide identification of plants and animals; a wheel of images could be rotated with a manual lever.

Intrigued, Graves believed the images could act as a postcard alternative, sold in photo and gift shops as souvenirs. Gruber, who had long wished to strike gold with one business idea or another—he once wanted to grow mushrooms for a living—agreed to license the idea to Sawyer’s. The plan was to have the View-Master ready for a 1939 debut at the World’s Fair.

Gruber’s suggestion to source the lenses from Germany would have unintended consequences. With a money trail seemingly incriminating him and witnesses who could testify about his opinion of Hitler, he was a prime target for J. Edgar Hoover's crackdown on subversives. While awaiting trial, the government banished Gruber to Idaho, where he kept up a written correspondence with Sawyer’s employees in an attempt to oversee the development of the viewer—and, occasionally, was granted permission to return to Oregon to solve production problems.

While it seems odd the government would want to indulge a self-admitted Nazi during wartime, they had good reason. In a roundabout way, Gruber was working for them.

While View-Master got a welcome reception from the general public in 1940, the rationing of film and paper made it an expendable product. Sawyer’s feared that it would never regain that momentum. But in a reversal of fortune, the U.S. military saw an opportunity: The View-Master was a perfect vehicle to show soldiers slides of aircraft and ammunition for easy identification. At virtually the same time Gruber was in potato-country exile, the armed forces purchased more than 10,000 View-Masters and 6 million reels. (Amid the educational slides, a few risqué pin-up images of Bettie Page found their way into circulation.)

It was word-of-mouth advertising Sawyer’s could never have dreamed of buying. All the GIs who were impressed by View-Master while deployed came home and told their families about it. Instead of packing the household in a car for a trip, they could spend $1 for a viewer with seven slides that transported them anywhere they wanted to go. View-Master was an album of vacation photos that didn’t require a vacation.

By this point, Gruber had returned to Portland and to his normal life. Despite his Nazi advocacy, a federal judge had found that he was not a spy or working for German forces and ordered that his case be dropped.

It was a dark chapter in the device’s history, but it wouldn’t be the worst.

 
Gruber, who returned to his photography work by training his lens on mushrooms and other eclectic science subjects, never intended View-Master to be a toy. To him, it was like a pair of binoculars that could peer deeply into images with amazing clarity and detail. Coin and stamp collectors could keep a library of samples; rare birds could be photographed and studied for distinctive traits.

But Sawyer’s also took note of how much appeal View-Master held for children. Beginning in 1944, the company hired a sculptor, Florence Thomas, to craft customized scenes from fairy tales and children’s stories that could be placed in a diorama and photographed. Thomas produced a series of images from A Christmas Carol, Alice in Wonderland, and the Bible. The reels were popular sellers and essentially doubled View-Master’s demographic.

In 1951, Sawyer’s purchased Tru-Vue, a competing stereoscopic viewer. While it was nice to eliminate the competition, Tru-Vue offered something even more valuable: a transferable license to Walt Disney’s character library.

Almost overnight, View-Master had access to images of Disney television series like Davy Crockett and movies like Bambi. At a time when color television was scarce and there was no such thing as a home video market, a child being able to revisit familiar characters—in Kodachrome color—was a big deal. The adventures of Donald Duck quickly eclipsed mushroom catalogs, though there was always an appetite for human subjects: the 1953 coronation of Queen Elizabeth II sold 1.5 million reels in just nine months.

While View-Master wound up changing hands several times over the years—Sawyer’s was acquired by General Aniline Film Corporation in 1966 before eventually winding up in the hands of Tyco in 1989—Gruber never had much to do with corporate maneuverings. His passion remained photography. Following his encounter with the government, he embarked on the most ambitious project of his life.

After returning to Portland, Gruber struck up a friendship with Dr. David Bassett, who was then teaching at the University of Washington before moving on to Stanford. With Bassett’s assistance, Gruber wanted to use the potent visual stimulus of the View-Master to record the human anatomy in exacting detail.

The project, A Stereoscopic Atlas of the Human Anatomy, used dissected cadaver tissue to highlight intricate maps of nerves, muscle, and tendons. Bassett and Gruber sliced open brains and spinal cords, logging an unprecedented tour of the body.

It was probably best Gruber was busy elsewhere. It would take decades, but the View-Master plant in Beaverton that had opened in 1951 was found to have concentrations of the degreaser trichloroethylene (TCE) more than 320 times the legal limit, much of it seeping into the well water that employees drank. Several fell ill; many self-reported diagnoses of cancer. It was closed permanently in 2001.

Of View-Master’s lesser scandal, Gruber made a fair pass at redeeming himself. When the extent of Hitler’s homicidal tendencies were revealed, Gruber realized he had been mistaken about the Führer’s leadership qualities and he no longer made his politics public business. Work on the Atlas consumed the remaining 14 years of his life until his death in 1965.

While View-Master is probably best known for its licensed entertainment properties in the 1970s and 1980s, its most lasting contribution may have come from a rehabilitated Nazi sympathizer. To this day, the Atlas and its 1500 images are considered to be one of the finest dissection projects ever captured on film.

The Body
10 Facts About the Appendix
Illustration by Mental Floss / Images: iStock

Despite some 500 years of study, the appendix might be one of the least understood structures in the human body. Here's what we know about this mysterious organ.

1. THE ANCIENT EGYPTIANS CALLED IT THE "WORM" OF THE BOWEL.

The human appendix is small, tube-shaped, and squishy, giving ancient Egyptians, who encountered it when preparing bodies for funerary rites, the impression of a worm. Even today, some medical texts refer to the organ as vermiform—Latin for "worm-like."

2. THE APPENDIX SHOWS UP IN LEONARDO DA VINCI’S DRAWINGS.

The earliest description of a human appendix was written by the Renaissance physician-anatomist Jacopo Berengario da Carpi in 1521. But before that, Leonardo da Vinci is believed to drawn the first depiction of the organ in his anatomical drawings in 1492. Leonardo claimed to have dissected 30 human corpses in his effort to understand the way the body worked from mechanical and physiological perspectives.

3. IT'S ABOUT THE SIZE OF A PINKY FINGER.

The appendix is a small pouch connected to the cecum—the beginning of the large intestine in the lower right-hand corner of your abdomen. The cecum’s job is to receive undigested food from the small intestine, absorb fluids and salts that remain after food is digested, and mix them with mucus for easier elimination; according to Mohamad Abouzeid, M.D., assistant professor and attending surgeon at NYU Langone Medical Center, the cecum and appendix have similar tissue structures.

4. CHARLES DARWIN THOUGHT IT WAS A VESTIGIAL ORGAN …

The appendix has an ill-deserved reputation as a vestigial organ—meaning that it allegedly evolved without a detectable function—and we can blame Charles Darwin for that. In the mid-19th century, the appendix had been identified only in humans and great apes. Darwin thought that our earlier ancestors ate mostly plants, and thus needed a large cecum in which to break down the tough fibers. He hypothesized that over time, apes and humans evolved to eat a more varied and easier-to-digest diet, and the cecum shrank accordingly. The appendix itself, Darwin believed, emerged from the folds of the wizened cecum without its own special purpose.

5. … BUT THE APPENDIX PROBABLY EVOLVED TO HELP IMMUNE FUNCTION.

The proximity and tissue similarities between the cecum and appendix suggest that the latter plays a part in the digestive process. But there’s one noticeable difference in the appendix that you can see only under a microscope. “[The appendix] has a high concentration of the immune cells within its walls,” Abouzeid tells Mental Floss.

Recent research into the appendix's connection to the immune system has suggested a few theories. In a 2015 study in Nature Immunology, Australian researchers discovered that a type of immune cells called innate lymphoid cells (ILCs) proliferate in the appendix and seem to encourage the repopulation of symbiotic bacteria in the gut. This action may help the gut recover from infections, which tend to wipe out fluids, nutrients, and good bacteria.

For a 2013 study examining the evolutionary rationale for the appendix in mammal species, researchers at Midwestern University and Duke University Medical Center concluded that the organ evolved at least 32 times among different lineages, but not in response to dietary or environmental factors.

The same researchers analyzed 533 mammal species for a 2017 study and found that those with appendices had more lymphatic (immune) tissue in the cecum. That suggests that the nearby appendix could serve as "a secondary immune organ," the researchers said in a statement. "Lymphatic tissue can also stimulate growth of some types of beneficial gut bacteria, providing further evidence that the appendix may serve as a 'safe house' for helpful gut bacteria." This good bacteria may help to replenish healthy flora in the gut after infection or illness.

6. ABOUT 7 PERCENT OF AMERICANS WILL GET APPENDICITIS DURING THEIR LIFETIMES.

For such a tiny organ, the appendix gets infected easily. According to Abouzeid, appendicitis occurs when the appendix gets plugged by hardened feces (called a fecalith or appendicolith), too much mucus, or the buildup of immune cells after a viral or bacterial infection. In the United States, the lifetime risk of getting appendicitis is one in 15, and incidence in newly developed countries is rising. It's most common in young adults, and most dangerous in the elderly.

When infected, the appendix swells up as pus fills its interior cavity. It can grow several times larger than its average 3-inch size: One inflamed appendix removed from a British man in 2004 measured just over 8 inches, while another specimen, reported in 2007 in the Journal of Clinical Pathology, measured 8.6 inches. People with appendicitis might feel generalized pain around the bellybutton that localizes on the right side of the abdomen, and experience nausea or vomiting, fever, or body aches. Some people also get diarrhea.

7. APPENDECTOMIES ARE ALMOST 100 PERCENT EFFECTIVE FOR TREATING APPENDICITIS.

Treatment for appendicitis can go two ways: appendectomy, a.k.a. surgical removal of the appendix, or a first line of antibiotics to treat the underlying infection. Appendectomies are more than 99 percent effective against recurring infection, since the organ itself is removed. (There have been cases of "stump appendicitis," where an incompletely removed appendix becomes infected, which often require further surgery.)

Studies show that antibiotics produce about a 72 percent initial success rate. “However, if you follow these patients out for about a year, they often get recurrent appendicitis,” Abouzeid says. One 2017 study in the World Journal of Surgery followed 710 appendicitis patients for a year after antibiotic treatment and found a 26.5 percent recurrence rate for subsequent infections.

8. AN INFECTED APPENDIX DOESN’T ACTUALLY BURST.

You might imagine a ruptured appendix, known formally as a perforation, being akin to the "chestbuster" scene in Alien. Abouzeid says it's not quite that dramatic, though it can be dangerous. When the appendix gets clogged, pressure builds inside the cavity of the appendix, called the lumen. That chokes off blood supply to certain tissues. “The tissue dies off and falls apart, and you get perforation,” Abouzeid says. But rather than exploding, the organ leaks fluids that can infect other tissues.

A burst appendix is a medical emergency. Sometimes the body can contain the infection in an abscess, Abouzeid says, which may be identified through CT scans or X-rays and treated with IV antibiotics. But if the infection is left untreated, it can spread to other parts of the abdomen, a serious condition called peritonitis. At that point, the infection can become life-threatening.

9. SURGEONS CAN REMOVE AN APPENDIX THROUGH A TINY INCISION.

In 1894, Charles McBurney, a surgeon at New York's Roosevelt Hospital, popularized an open-cavity, muscle-splitting technique [PDF] to remove an infected appendix, which is now called an open appendectomy. Surgeons continued to use McBurney's method until the advent of laparoscopic surgery, a less invasive method in which the doctor makes small cuts in the patient's abdomen and threads a thin tube with a camera and surgical tools into the incisions. The appendix is removed through one of those incisions, which are usually less than an inch in length.

The first laparoscopic appendectomies were performed by German physician Kurt Semm in the early 1980s. Since then, laparoscopic appendectomies have become the standard treatment for uncomplicated appendicitis. For more serious infections, open appendectomies are still performed.

10. AN APPENDIX ONCE POSTPONED A ROYAL CORONATION.

When the future King Edward VII of Great Britain came down with appendicitis (or "perityphlitis," as it was called back then) in June 1902, mortality rates for the disease were as high as 26 percent. It was about two weeks before his scheduled coronation on June 26, 1902, and Edward resisted having an appendectomy, which was then a relatively new procedure. But surgeon and appendicitis expert Frederick Treves made clear that Edward would probably die without it. Treves drained Edward's infected abscess, without removing the organ, at Buckingham Palace; Edward recovered and was crowned on August 9, 1902.

11. THE WORLD'S LONGEST APPENDIX MEASURED MORE THAN 10 INCHES.

On August 26, 2006, during an autopsy at a Zagreb, Croatia hospital, surgeons obtained a 10.24-inch appendix from 72-year-old Safranco August. The deceased currently holds the Guinness World Record for "largest appendix removed."

13 Incredible Facts About Frederick Douglass

The list of Frederick Douglass's accomplishments is astonishing—respected orator, famous writer, abolitionist, civil rights leader, presidential consultant—even without considering that he was a former slave with no formal education. In honor of his birth 200 years ago, here are 13 incredible facts about the life of Frederick Douglass.

1. HE BARTERED BREAD FOR KNOWLEDGE.

Because Douglass was a slave, he wasn't allowed to learn to read or write. A wife of a Baltimore slave owner did teach him the alphabet when he was around 12, but she stopped after her husband interfered. Young Douglass took matters into his own hands, cleverly fitting in a reading lesson whenever he was on the street running errands for his owner. As he detailed in his autobiography, Narrative of the Life of Frederick Douglass, he'd carry a book with him while out and about and trade small pieces of bread to the white kids in his neighborhood, asking them to help him learn to read the book in exchange.

2. HE CREDITED A SCHOOLBOOK FOR SHAPING HIS VIEWS ON HUMAN RIGHTS.

During his youth, Douglass obtained a copy of The Columbian Orator, a collection of essays, dialogues, and speeches on a range of subjects, including slavery. Published in 1797, the Orator was required reading for most schoolchildren in the 1800s and featured 84 selections from authors like Cicero and Milton. Abraham Lincoln was also influenced by the collection when he was first starting in politics.

3. HE TAUGHT OTHER SLAVES TO READ.

While he was hired out to a farmer named William Freeland, a teenaged Douglass taught fellow slaves to read the New Testament—but a mob of locals soon broke up the classes. Undeterred, Douglas began the classes again, sometimes teaching as many as 40 people.

4. HIS FIRST WIFE HELPED HIM ESCAPE FROM SLAVERY.

Anna Murray was an independent laundress in Baltimore and met Douglass at some point in the mid-1830s. Together they hatched a plan, and one night in 1838, Douglass took a northbound train clothed in a sailor's uniform procured by Anna, with money from her savings in his pocket alongside papers from a sailor friend. About 24 hours later, he arrived in Manhattan a free man. Anna soon joined him, and they married on September 15, 1838.

5. HE CALLED OUT HIS FORMER OWNER.

In an 1848 open letter in the newspaper he owned and published, The North Star, Douglass wrote passionately about the evils of slavery to his former owner, Thomas Auld, saying "I am your fellow man, but not your slave." He also inquired after his family members who were still enslaved a decade after his escape.

6. HE TOOK HIS NAME FROM A POEM.

He was born Frederick Augustus Washington Bailey, but after escaping slavery, Douglass used assumed names to avoid detection. Arriving in New Bedford, Massachusetts, Douglass, then using the surname "Johnson," felt there were too many other Johnsons in the area to distinguish himself. He asked his host (ironically named Nathan Johnson) to suggest a new name, and Mr. Johnson came up with Douglas, a character in Sir Walter Scott's poem The Lady of the Lake.

7. HE'S CALLED THE 19TH CENTURY'S MOST PHOTOGRAPHED AMERICAN.

There are 160 separate portraits of Douglass, more than Abraham Lincoln or Walt Whitman, two other heroes of the 19th century. Douglass wrote extensively on the subject during the Civil War, calling photography a "democratic art" that could finally represent black people as humans rather than "things." He gave his portraits away at talks and lectures, hoping his image could change the common perceptions of black men.

8. HE REFUSED TO CELEBRATE THE 4TH OF JULY.

Douglass was well-known as a powerful orator, and his July 5, 1852 speech to a group of hundreds of abolitionists in Rochester, New York, is considered a masterwork. Entitled "What to the Slave is the Fourth of July," the speech ridiculed the audience for inviting a former slave to speak at a celebration of the country who enslaved him. "This Fourth [of] July is yours, not mine," he famously said to those in attendance. "Do you mean, citizens, to mock me, by asking me to speak to-day?" Douglass refused to celebrate the holiday until all slaves were emancipated and laws like the Compromise of 1850, which required citizens (including northerners) to return runaway slaves to their owners, were negated.

9. HE RECRUITED BLACK SOLDIERS FOR THE CIVIL WAR.

Douglass was a famous abolitionist by the time the war began in 1861. He actively petitioned President Lincoln to allow black troops in the Union army, writing in his newspaper: "Let the slaves and free colored people be called into service, and formed into a liberating army, to march into the South and raise the banner of Emancipation among the slaves." After Lincoln signed the Emancipation Proclamation, Douglass worked tirelessly to enlist black soldiers, and two of his sons would join the 54th Massachusetts Regiment, famous for its contributions in the brutal battle of Fort Wagner.

10. HE SERVED UNDER FIVE PRESIDENTS.

Later in life, Douglass became more of a statesman, serving in highly appointed federal positions, including U.S. Marshal for D.C., Recorder of Deeds for D.C., and Minister Resident and Consul General to Haiti. Rutherford B. Hayes was the first to appoint Douglass to a position in 1877, and Presidents Garfield, Arthur, Cleveland, and Benjamin Harrison each sought his counsel in various positions as well.

11. HE WAS NOMINATED FOR VICE PRESIDENT OF THE UNITED STATES.

As part of the Equal Rights Party ticket in 1872, Douglass was nominated as a VP candidate, with Victoria Woodhull as the Presidential candidate. (Woodhull was the first-ever female presidential candidate, which is why Hillary Clinton was called "the first female presidential candidate from a major party" during the 2016 election.) However, the nomination was made without his consent, and Douglass never acknowledged it (and Woodhull's candidacy itself is controversial because she wouldn't have been old enough to be president on Inauguration Day). Also, though he was never a presidential candidate, he did receive one vote at each of two nomination conventions.

12. HIS SECOND MARRIAGE STIRRED UP CONTROVERSY.

Two years after his first wife, Anna, died of a stroke in 1882, Douglass married Helen Pitts, a white abolitionist and feminist who was 20 years younger than him. Even though she was the daughter of an abolitionist, Pitts's family (which had ancestral ties directly to the Mayflower) disapproved and disowned her—showing just how taboo interracial marriage was at the time. The black community also questioned why their most prominent spokesperson chose to marry a white woman, regardless of her politics. But despite the public's and their families' reaction, the Douglasses had a happy marriage and were together until his death in 1895 of a heart attack.

13. AFTER EARLY SUCCESS, HIS NARRATIVE WENT OUT OF PRINT.

Narrative of the Life of Frederick Douglass, An American Slave, Written by Himself, his seminal autobiography, was heralded a success when it came out in 1845, with some estimating that 5000 copies sold in the first few months; the book was also popular in Ireland and Britain. But post-Civil War, as the country moved toward reconciliation and slave narratives fell out favor, the book went out of print. The first modern publication appeared in 1960—during another important era for the fight for civil rights. It is now available for free online.
