Hashime Murayama and the Art of Saving Lives | Science History Institute
“Thus began one of the most important collaborations in the history of cancer research. While Papanicolaou squinted at cells, Murayama drew them and charted the course of cancer. To do the artwork he relied on what’s called a camera lucida. This device uses a lens and prism to superimpose an image of what the artist wants to draw—such as cells under a microscope—onto a piece of paper. Murayama had always loved technology, and the camera lucida aided him in producing accurate sketches of cells.”
