Louis Magaziner was a native of Hungary who came to the United States with his parents, Henry and Cecelia (Rosenbluth) Magaziner in 1887. He graduated from Central High School in 1896 and received his B.S. in Architecture from the University of Pennsylvania in 1900. He was a classmate and friend of Julian Abele (class of 1902).^[11]

Magaziner worked at firms including Frederick Mann, Cope & Stewardson, Albert Kelsey, and Newman & Harris (as head draftsman) before establishing his own firm, Magaziner & Potter, with William Woodburn Potter in 1907. The firm lasted until 1917 and was followed up by other partnerships including Magaziner & Eberhard; Magaziner, Eberhard & Harris, and Louis & Henry Magaziner. His firms produced theaters, mansions, colleges, hospitals, clubs, and banks. Magaziner became a member of the American Institute of Architects in 1942; practiced in Pennsylvania, New Jersey, and Ohio; and was a founder of the Homewood School (formerly known as the Hebrew Sheltering Home).^[12]

His son Henry Jonas Magaziner was a prominent preservationist, author and architect. Father and son practiced architecture when not interrupted by the Great Depression and World War II, before Henry set off on his own as an architect and then preservationist and author. He wrote the books The Golden Age of Iron Work and Our Liberty Bell.^[13][14] The Henry Magaziner Award is given by the Philadelphia branch of the American Institutes for Architecture.^[14][15]
