- This is a large binocular dissecting instrument with triple nosepiece. The stage is marked “SPENCER / BUFFALO / U.S.A.” and the arm is marked “242043.” This serial number indicates a date of 1945. This was used by Min-Chuan Chang (1908-1991), a biologist who was born in China and educated in Britain, and who arrived in the United States in 1945. Working with Gregory Pincus at the Worcester Foundation for Experimental Biology, Chang pioneered the field of in vitro fertilization, co-discovered the birth control pill, and made other contributions to the field of reproductive biology.
