Jacob Lionel Bakst Cooper — In Memoriam

Abstract

We are here together to pay tribute¹⁾ to Professor Lionel Cooper. He was born in Beaufort-West in the Republic of South Africa on 27. Dec. 1915. After receiving his B.Sc. degree at the University of Cape Town in 1935, he came to England as a Rhodes scholar to study at Oxford University. He wrote his doctoral dissertation under the direction of Professor E.C. Titchmarsh, and received his D.Phil. in 1940. In 1939/44 he published three papers on Fourier integrals, and shortly thereafter he wrote three further papers on operators in Hilbert space, including one on semigroup operators (Oxford Quart. J., Ann. of Math., PLMS; 1945–8); The latter three papers are cited inmost books on functional analysis and established his early reputation.
