Premise: Adolph Heinrich Joseph Sutro (April 29, 1830 – August 8, 1898) was a German-American engineer, politician and philanthropist who served as the 24th mayor of San Francisco from 1895 until 1897. Born a German Jew, he moved to Virginia City, Nevada and made a fortune at the Comstock Lode. He is today perhaps best remembered for the various San Francisco lands and landmarks that still bear his name.
Hypothesis: Suro was a mayor during 1896 but was not a mayor in 1898.
