Thomas Nast (1840-1902) is often considered America's leading political cartoonist. He is especially known for his withering portraits of William Marcy ("Boss") Tweed and the members of his "Ring" of Tammany Hall politicians who ruled New York City in the late 1860s. Nast is also notorious for his anti-Catholic cartoons which contributed to a renewed wave of anti-immigrant sentiment in the 1870s. Nast's Almanac was very popular and the 1871 volume contained humorist G. P. Webster's poem, "A Dream of the Period" with Nast's illustrations. Together the poem and the drawings say a good deal about conventional notions of gender and gender roles.
