Chueh Chang (simplified Chinese: 张明觉; traditional Chinese: 張明覺; pinyin: Zhāng Míngjué,

October 10, 1908 – June 5, 1991), often credited as M.C. Chang, was

a Chinese-American reproductive biologist.

His specific area of study was the fertilisation process in mammalian reproduction.

Though his career produced findings that are important and valuable to many

areas in the field of fertilisation, including his work on in vitro fertilisation which led to the first "test tube baby", he was best known to the world for his

contribution to the development of the combined oral

contraceptive pill at the Worcester

Foundation for Experimental Biology. Chang was born on October 10,

1908, in the village of Dunhòu (敦厚), which lies 64 miles (103 km) northwest

of Taiyuan, the capital city of Shanxi province, in Qing dynasty China. His family was able to provide for him a good

education, and in 1933, he obtained a bachelor's degree in animal psychology from Tsinghua University in

Beijing. In 1938, Chang won a national competition and was awarded one of the

few available fellowships to study abroad. He went to spend a year at the University of Edinburgh studying agricultural science, but

found that the University was not to his liking due to a combination of the

cold weather and a perceived bias against foreigners there. On an invitation from Arthur

Walton, Chang left the University of Edinburgh and went on to College,

Cambridge. With his newfound interest in reproductive biology,

Chang immersed himself in research, working together with other scientists such

as John Hammond and F.H.A. Marshall,

under the tutelage of Arthur Walton. In 1941, he was awarded a PhD in animal breeding by the University of Cambridge on his

observations on the effect of testicular cooling and various hormonal

treatments on the respiration, metabolism, and survival of sperm in animals. Chang

met his wife, American-born Chinese Isabelle

Chin Chang, in the library at Yale University, shortly after he moved to the United States. Chin assumed the role of the housewife in the

pair's marriage, allowing Chang to delve into his work without domestic

concerns. They have two daughters and a son together –

Claudia Chang Tourtellotte, head of the anthropology department at Sweet Briar College; Pamela O'Malley Chang, an architect, civil

engineer, and sustainable design consultant and Francis Hugh Chang, director of health

centers in Boston, Massachusetts. and San Jose, California. Upon his death,

Chang was buried in Shrewsbury, Massachusetts,

where he had lived and where the Worcester

Foundation for Experimental Biology was located.
