John Douglass Ferry (May 4, 1912 – October 18, 2002) was a Canadian-born American chemist and biochemist noted for development of surgical products from blood plasma and for studies of the chemistry of large molecules.
[1][2][3][4] Along with Williams and Landel, Ferry co-authored the work on time-temperature superposition in which the now famous WLF equation first appeared.
[2] The University of Wisconsin said that he was "undoubtedly the most widely recognized research pioneer in the study of motional dynamics in macromolecular systems by viscoelastic techniques".
[3][4] Ferry was born in Dawson City, Yukon Territory, Canada,[5] and attended a one-room school in Murray, Idaho.
[2] At age 19, Ferry received his bachelor of arts degree at Stanford University in 1932.
