Arthur Leonard Schawlow belongs to the record of physics as one of those whose work outlasted the questions that prompted it.
Arthur Leonard Schawlow was born in 1921. His recorded nationality is United States.
Twentieth-century science was collaborative, expensive and political: the questions were pursued by teams, and the answers had consequences that reached well past the laboratory.
Physics advances when somebody insists on measuring what everyone else has been content to assume.
That the work was done from United States matters to the story. Science has never been evenly distributed, and where a person is based has always shaped which problems are reachable and whose results get read.
What that record amounts to is a body of physics that later workers could build on without re-checking. That is the practical test of a scientific life, and it is a harder one than fame.
Some of his own words survive, and they are collected on this page below.
Arthur Leonard Schawlow died in 1999, aged 78. What survives is not the reputation but the result: the part of physics that no longer has to be argued for.
