P.H. McCarthy

Patrick Henry McCarthy (1863 - 1933) was a powerful labor leader in San Francisco and served as Mayor from 1910 to 1912. He was more commonly known as P.H. McCarthy and sometimes by the nickname "Pinhead." Olaf Tveitmoe gained power in San Francisco in part because of his close association with McCarthy. McCarthy was born in County Limerick, Ireland and came to the United States in 1880.
