Marshall Krause served as lead attorney for the ACLU of Northern California from 1960 through 1968 and subsequently served as an attorney in private practice where he continued to work civil liberties cases. Krause attended UCLA as an undergraduate and graduated from Boalt Hall, UC Berkeley School of Law after which he clerked for Judge William Denman and Justice Phil Gibson. In this oral history, Mr. Krause discusses: his upbringing and education, including his time at Boalt Hall; clerkships with Denman and Gibson and how those experiences influenced his progressive attitudes; his tenure as ACLU staff attorney, including many of the cases he worked; his experiences arguing several cases before the United States Supreme Court; his perspective of the San Francisco counterculture of the 1960s; and his professional and legal career after leaving ACLU in 1968, which included arguing additional cases before the US Supreme Court.
