The Holmes Stereoscope is a wooden or metal viewer with two prismatic lenses and a stand to hold the stereo card.<\/p>\n <\/p>\n Stereoscope cards have two photos taken with the same focal point, but from different angles. When you look through a viewer, it looks like a single 3-D picture. They were very popular and you could find them anywhere.<\/p>\n These are at the entrance to Lewis & Clark Caverns. You can view them while you wait for your tour.<\/p>\n More about our visit to Lewis & Clark Caverns ><\/a> You can buy Stereoscopes and Stereoviews<\/span> on eBay ><\/a><\/p>\n I used to make 3-D photos and you can too. Just pick something in the background to focus on. Then step to one side, focus on exactly the same background and take the next photo. I made my first viewer out of a cold cereal box with a slot to hold the card and a piece of another box taped in the middle. Google has a template for a paper stereoscope, Google Cardboard.<\/p>\n Google Cardboard ><\/a><\/p>\n In 1939 View-Master patented a stereoscope with cardboard discs holding transparent film photos.<\/p>\n You can now get stereoscopes to hold an iPhone or iPod Touch. View-Master has Virtual Reality apps that work on a smartphone. <\/span><\/p>\n Viewmaster Products on Amazon ><\/a><\/p>\n Oliver Wendell Holmes was the father of the U. S. Supreme Court Justice, Oliver Wendell Holmes Jr. He was an author, poet, physician, professor, lecturer and inventor.<\/p>\n He was a medical reformer. Holmes promoted the benefits of using the stethoscope and lectured widely exposing medical fallacies, or “quackeries”. He spoke out strongly against false reasoning and misrepresentation of evidence in his lectures Astrology and Alchemy<\/em>, Medical Delusions of the Past<\/em> and Homeopathy and Its Kindred Delusions<\/em>.<\/p>\n Before Germ Theory of Disease was discovered, Holmes recognized that infections were contagious and advocated purifying instruments.\u00a0 He coined the word “anesthesia” in a letter to William T. G. Morton, the first person to publicly demonstrate the use of ether in surgery.<\/p>\n Oliver Wendell Holmes stood up to criticism attempting to grant admission to the first woman and the first African-American men to Harvard Medical School. \u00a0(Harriot Kezia Hunt later withdrew her application due to strong pressure from other students, university overseers and other faculty members. Martin Delany and two other black men were admitted, but bowing to pressure only persevered for one semester.)<\/p>\n Oliver Wendell Holmes was called as an expert for both sides in the Parkman\u2013Webster murder case, the first time forensic evidence was accepted to identify a body. This was the first time in the United States that dental evidence and scientific testimony were accepted in a murder trial. (The murdered man\u2019s widow empathized with the wife and daughters of the murderer because they were vilified by the press. She was the first contributor to a fund created to benefit the convicted man\u2019s impoverished family.) A number of books have been written retelling the story.<\/p>\n![\"The](\"https:\/\/i0.wp.com\/www.design42.com\/caving\/blog\/wp-content\/uploads\/2016\/12\/Holmes_stereoscope_with_card.jpg?ssl=1\")

He did not patent it, so that it could be produced inexpensively.<\/figcaption><\/figure>\n<\/a>
