Cheers to 80 years of Block O

This student organization is faithfully carrying out the mission of its founder.

Ohio State football had a noise problem. “Fellows bringing girls to the games get sophisticated and just sit back as spectators,” cheerleader Ralph Telfer lamented to The Lantern in 1937. His solution: a dedicated section of “dyed-in-the-wool rooters” to lead cheers and do card stunts. The next year, fellow cheerleader Clancy Isaac got Block O off the ground, and 80 years later, it’s still a vital thread in the fabric of Buckeye spirit.

Expanded to cover cheering sections for 11 sports, Block O unites students from every corner of the university, says senior finance major James Prisco, the group’s president. “The passion for Ohio State sports is such a cool thing to be a part of,” he says. “And we have a great time.”

Several card tricks are still done at every home game, and landing one of the coveted 2,000-plus Block O seats is as tough as ever. “Here’s to another 80 years,” Prisco says.


Cheerleader Clancy Isaac launches Block O for the Oct. 1 game against Indiana. Seats run from midfield to the 20-yard line, and scarlet and gray cloth capes and cards are employed. By 1940, the section comprises 1,200 fans using 3,000 colored cards.


After Block O fades away during World War II and revivals sputter, the cheering section is successfully reintroduced by Ohio Staters Inc.

Brutus Buckeye makes his first appearance with a papier-mâché head. A sturdier fiberglass Brutus head is created and turned over to Block O until 1974, when the university takes responsibility for the mascot.

The 50th anniversary of Block O warrants a special live TV appearance and a huge cake at a party on Lane Avenue.
