content: The Intermatic Time-All was made by International Register Co., in Chicago, and on the market by 1970. This example, a Model a211-6, came from the laboratory of Min-Chuah Chang (1908-1991), a biologist from China who was educated in Britain, and 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.
