Rudolph Ruzicka (29 June 1883 – 20 July 1978) was a Czech-born American wood engraver, etcher, illustrator, typeface designer, and book designer. Ruzicka designed typefaces and wood engraving illustrations for Daniel Berkeley Updike's Merrymount Press, and was a designer for, and consultant to, the Mergenthaler Linotype Company for fifty years. He designed a number of seals and medals, including the American Institute of Graphic Arts (AIGA) and the Dartmouth Medal of the American Library Association.
Rudolph Ruzicka was born in Bohemia in 1883. He emigrated to the United States of America at age ten, living first in Chicago where he took drawing lessons at the Hull House School before becoming an apprentice wood engraver. From 1900 to 1902 he attended further classes at the Art Institute of Chicago. In 1903 he moved to New York to work as an engraver at the American Bank Note Company and at Calkins & Holden. In subsequent years he attended classes at both the Art Students League of New York and the New York School of Art.
In 1910 Ruzicka set up his own shop at 954 Lexington Avenue in New York City. He received his first major art commission from System magazine. Many exhibitions followed, including such venues as the Societe de la Gravure, Paris, the Grolier Club, and the Century Association, New York. In 1916 Ruzicka built a house and a workshop in Dobbs Ferry, New York.
