W. Willard (Bill) Wirtz was a lawyer, an arbitrator, a law professor, and served as undersecretary and secretary of labor under Presidents Kennedy and Johnson.

Willard Wirtz Collection on Adlai Stevenson documents Stevenson's campaigns for president in 1952 and 1956, as well as Stevenson's political activities in 1960 and in between campaigns. Because Wirtz was a speechwriter in 1952, in charge of speech content in 1956, and a close advisor and occasional speechwriter at other times, this collection most strongly documents the campaign activities of drafting speeches and fine-tuning campaign policy.
