Elizabeth MacGregor Hardy (born July 31, 1915 - died June 26, 2008)[1] was a North American chemist who discovered the Cope rearrangement while working in Arthur Cope's research group at Bryn Mawr College.[2][3][4] The rearrangement drew upon the electronic models of and Christopher Kelk Ingold, but also the non-electronic work of Rainer Ludwig Claisen and .[5]

Early life and education[]

Elizabeth MacGregor Hardy was born in Ottawa, Ontario, Canada to parents Thomas Woodburne Hardy and Margaret Ada (Graham) Hardy. Hardy attended McGill University and graduated with a Bachelor in Science in 1938.[6] In 1939, Hardy obtained a Master of Arts degree from Bryn Mawr College. She went on to do a Ph.D.(organic chemistry) at Bryn Mawr College with Arthur C. Cope, which she completed in 1942.[7] Graduate students Elizabeth Hardy and coauthored nearly half of Cope's papers from Bryn Mawr.[8]

Hardy went on to work for American Cyanamid.[7]

Career and research[]

Elizabeth MacGregor Hardy worked as assistant professor of Organic Chemistry at Bryn Mawr College in 1939 and 1940. In the years 1942–1958, Hardy worked as a chemist at , subsequently she worked as a literature chemist at from 1958 to 1975. After working for , Hardy worked as a senior resident literature chemist for American Cyanamid Company from 1975 on.[6] She was a member of the American Association for the Advancement of Science, American Chemical Society and Chemical Institute of Canada. Hardy worked in a number of different research areas including molecular rearrangements, preparation of unsaturated esters and ketones, vat dyestuffs, esterification of leuco vat dyes, organic sulfur compounds, and pharmaceutical chemistry.
