BRODERICK, David Colbreth, senator, born in Washington, District of Columbia, 4 February, 1820: died near Lake Merced, California, 16 September, 1859. His father, who had emigrated from Ireland, was employed in cutting stone for the capitol. In 1823 the family removed to New York, where young Broderick received a public-school education, after which he was apprenticed to learn the stone-cutter's trade. He became actively connected with the volunteer fire department of New York, and at the same time acquired considerable political influence. In 1846 he was defeated as a democratic candidate for congress from New York. Three years later he went to California, where he at once became prominent in politics. In 1849 he was a member of the California constitutional convention, he was elected to the state senate in 1850 and again in 1851, when he became the presiding officer of that body. In 1856 he was elected United States senator from California, serving from 4 March, 1857, until his death. He was eminent as a debater, opposed the admission of Kansas as a state under the Le-compton constitution, and became separated from the Democratic Party on the slavery question in 1858. His death resulted from a wound received in a duel fought with David S. Terry, chief justice of the Supreme Court of California. Political differences and personal abuse in public speeches, of which Terry and Broderick were about equally guilty, led to the duel. Judge Terry was the challenger. Mr. Broderick fell at the first fire, his own pistol being discharged before he could level it.
