Query: Erich Leo Lehmann---A glimpse into his life and work   Through the use of a system-building approach, an approach that includes
finding common ground for the various philosophical paradigms within
statistics, Erich L. Lehmann is responsible for much of the synthesis of
classical statistical knowledge that developed from the Neyman--Pearson--Wald
school. A biographical sketch and a brief summary of some of his many
contributions are presented here. His complete bibliography is also included
and the references present many other sources of information on his life and
his work.
