Glenville High School

By the end of World War I, the neighborhood of Glenville became a home for an increasing number of Jewish European immigrants, and by the Great Depression was the epicenter of Cleveland's Jewish community.

Glenville High School was originally located at the intersection of Everton and Parkwood. In 1936, Glenville graduate Wilson Hirschfeld began work delivering papers within the offices of the Plain Dealer. Hirschfeld had been the editor of the Glenville student paper, The Torch and would work to become the Plain Dealer's managing editor.

Howard Metzenbaum ('35) was raised a businessman who lost his business in the Depression and a mother who earned $13 a week in a department store. He made his fortune through a parking lot franchise and spent many years as an Ohio Senator.

Willie Gilbert ('34) became a comedy writer, co-authoring the book for How to Succeed in Business Without Really Trying and writing for Howdy Doody as well as a variety of Hanna Barbera cartoons.

Jerome Lawrence (born Jerome Schwartz, class of 1933) co-wrote the play Inherit the Wind and The Night Thoreau Spent In Jail among many others.

Barney Silver (born Bernard Schrader, class of 32) founded the sketch comedy troupe The Times, pioneering improvisational club improv.

As has already been noted, Superman creators Joe Shuster and Jerry Siegel graduated from Glenville High in 1932.

Jerry Siegel & Joe Shuster

Jerome "Jerry" Siegel (October 17, 1914 – January 28, 1996) and Joseph "Joe" Shuster (July 10, 1914 - July 30, 1992) created Superman.

Joe and Jerry lived in the Glenville neighborhood and met attending Glenville High School, Class of 1932. Jerry wrote for The Torch, the school paper, and though he was shy and not terribly popular he was appreciated by the student body for his Tarzan parody, Goober the Mighty.

Joe was Canadian-born, moving with his family to Cleveland when he was 10. His eyesight was always terrible, and this is only one of the ways in which his artwork is so remarkable.

Jerry was born in Cleveland, his father owned a clothing store. His father died of a heart attack while the store was being robbed.

In 1934, after tossing an idea over and over in his head all night, repeatedly getting out of bed to hammer out more details, Siegel came up with the idea of a power, benevolent space-alien that resembled a man and came to Earth to protect people from criminals. Shuster drew the panels for a comic strip and they attempted to peddle it to publishers for four years before getting an offer to adapt it into a "comic" book format in 1938.

Shuster claims the hero, Superman, was meant to resemble Douglas Fairbanks, Jr., while his alter-ego Clark Kent was to look more like Harold Lloyd.
