“Emma Lehmer: A collaborator of Dick Lehmer’s in more senses than one, she is also a known and respected mathematical translator; we must be grateful to her, in particular, for translating Pontrjagin’s Topological groups.” —Paul R. Halmos, I Have a Photographic Memory
Emma Lehmer wrote around 60 papers on different aspects of number theory, about 20 of these being joint publications with her husband, Derrick Henry Lehmer. Their initial collaboration began as a three-way one with Lehmer working with both her husband and her father-in-law, Derrick Norman Lehmer. Her collaborations were both over deep mathematical results, as well as developing computers and computational methods to assist in solving number theory problems.
