Leo Pfeffer (1909–1993), one of the twentieth century’s most active litigators on church-state issues, was a prolific writer who advocated religious liberty and strict separation of church and state.

 

Among his books are Church, State, and Freedom (rev. ed., 1967) and Religion, State, and the Burger Court (1985).

 

Pfeffer served at Commission on Law and Social Action of the American Jewish Congress

 

Born in Hungary, the son of a rabbi, Pfeffer immigrated with his parents to New York City when he was two. After attending a secondary school that later became Yeshiva University, he earned a bachelor’s degree at New York’s City College and a law degree from New York University.

 

Beginning in 1945, he served for most of his career in various staff positions at the Commission on Law and Social Action of the American Jewish Congress, which litigated for separation of church and state. He lectured at several universities and was as an attorney for the New York Committee for Public Education and Religious Liberty.

 

Pfeffer argued several First Amendment church-state cases

 

In Illinois ex rel. McCollum v. Board of Education (1948), Pfeffer successfully argued against the “released time” program in schools, in which students were given time for religious instruction. (Pfeffer’s parents had withdrawn him from public schools after confronting a similar program.)

 

He filed amicus curiae briefs opposing public school prayer in Engel v. Vitale (1962), against Bible reading in Abington School District v. Schempp (1963), and against posting the Ten Commandments in schoolrooms in Stone v. Graham (1980).

 

He opposed the child benefit theory, on the basis of which states sometimes funneled money to families for textbooks and other expenses incurred as part of a parochial school education.

 

He presented arguments in an amicus brief in Lemon v. Kurtzman (1971), which led the Supreme Court to develop its three-part Lemon test that established rules for legislation concerning religion.

 

He was less successful in persuading the Court, in Tilton v. Richardson (1971), to oppose all aid to religious colleges and universities.

 

Pfeffer also opposed blue laws, which restricted people’s activities on Sunday, and defended conscientious objectors.
