Overview
John White Geary (December 30, 1819February 8, 1873) was an American lawyer, politician, Freemason, and a Union general in the American Civil War. He was the final alcalde and first mayor of San Francisco, a governor of the Kansas Territory, and the 16th governor of Pennsylvania.
Early years
Geary was born near Mount Pleasant, Pennsylvania, in Westmoreland County—in what is today the Pittsburgh metropolitan area. He was the son of Richard Geary, an ironmaster and schoolmaster of Scotch-Irish descent, and Margaret White, a native of Maryland. Starting at the age of 14, he attended nearby Jefferson College in Canonsburg, Pennsylvania, studying civil engineering and law, but was forced to leave before graduation due to the death of his father, whose debts he assumed. He worked at a variety of jobs, including as a surveyor and land speculator in Kentucky, earning enough to return to college and graduate in 1841. He worked as a construction engineer for the Allegheny Portage Railroad. In 1843, he married Margaret Ann Logan, with whom he had several sons, but she died in 1853. Geary then married the widowed Mary Church Henderson in 1858 in Carlisle, Pennsylvania.
Geary was active in the state militia as a teenager. In December 1846, during the Mexican–American War, he was commissioned in the 2nd Pennsylvania Infantry, serving as lieutenant colonel. He led the regiment heroically at Chapultepec, and was wounded five times in the process. Geary was an excellent target for enemy fire: a huge man for that era, he stood six feet six inches tall, 260 pounds (118 kg) and solidly built. Altogether, he was wounded at least ten times in his military career. Geary's exploits at Belén Gate earned him the rank of colonel and he returned home a war hero.
California politics
Moving west, Geary was appointed postmaster of San Francisco by President James K. Polk on January 22, 1849, and on January 8 1850, he was elected the city's alcalde, before California became a state, and then the first mayor of the city. Aged thirty at the time of his appointment, he holds the record as the youngest mayor in San Francisco history. As alcalde, he served as the city's judge in addition to the city's mayor. Geary returned to Pennsylvania in 1852 because of his wife's failing health. After her death, President Franklin Pierce wanted to appoint him governor of the Utah Territory, but Geary declined.
