Heinrich Kleisli worked in mathematics at a period when the field's own foundations were under discussion.
The record lists Heinrich Kleisli as mathematician (1930-2011).
Heinrich Kleisli was born at Niederweningen in 1930. His recorded nationality is Switzerland. He studied at ETH Zurich.
Twentieth-century mathematics became abstract and highly specialised, and its methods reached into physics, economics and computing.
His academic posts were held at University of Ottawa and University of Fribourg.
A theorem is permanent in a way no experiment can be, which raises the standard for entry.
That the work was done from Switzerland matters: mathematical training, institutions and the language of publication have never been evenly distributed.
Heinrich Kleisli died in 2011, aged 81. The proofs remain, and a proof does not decay - which is the particular permanence mathematics offers.
