He was a member of the New York Press Club and Lotos Club. Born in Yorkshire, England, he emigrated to the United States at age six. His notable work included support of William McKinley's 1896 presidential campaign. The younger brother of famed cartoonist Bernhard Gillam, he signed his work "Victor" or "F.

John C. Calhoun John Caldwell Calhoun ( ; March 18, 1782March 31, 1850) was an American statesman and political theorist from South Carolina, and the seventh Vice President of the United States from 1825 to 1832. He is remembered for strongly defending slavery and for advancing the concept of minority rights in politics, which he did in the context of defending white Southern interests from perceived Northern threats. He began his political career as a nationalist, modernizer, and proponent of a strong national government and protective tariffs. By the late 1820s, his views reversed and he became a leading proponent of states' rights, limited government, nullification, and opposition to high tariffs—he saw Northern acceptance of these policies as the only way to keep the South in the Union. His beliefs and warnings heavily influenced the South's secession from the Union in 1860–1861.
