  This article addresses shortcomings in the existing secondary literature
describing the nature and involvement of computing at the World War II Los
Alamos Lab. Utilizing rarely used source materials, and identifying points of
bias among more commonly used sources, this article provides a more complete
representation of wartime Los Alamos' computing operations and personnel,
including the Lab's typically under-represented human computers, and how they
contributed to the success of the Trinity test. This article also identifies
how the Lab's unusual wartime computing demands served as a formative
experience among many Los Alamos personnel and consultants, who contributed
significantly to the development and use of mechanized computing at and beyond
Los Alamos after the war.
