J. Barry Mahool (September 14, 1870 – July 29, 1935) was the Mayor of Baltimore from 1907-1911.
Mahool was born in Baltimore County on September 24, 1870. He became the Democratic nominee for Baltimore mayor in April 1907, defeating opponents John Charles Linthicum and George Stewart Brown. In May 1907, he defeated incumbent Republican mayor E. Clay Timanus.
In 1910, Mahool signed city ordinance No. 610 prohibiting African-Americans from moving onto blocks where whites were the majority, and vice versa. Mahool had been an advocate for social justice, championing causes such as woman’s suffrage, but the ordinance came in response to an uproar after George W.F. McMechen, an African-American Yale law school graduate, moved into a rich (white) neighborhood. The ordinance was rapidly declared unconstitutional.
Mahool lost a re-election bid in 1911 in the primary, losing to James H. Preston.
Mahool died in Baltimore on July 29, 1935, nine days after suffering a fall in Ocean City, Maryland.
