Carl Leffler

All wasn't smooth with Edwin S. Lowe's Bingo card development. It was found that at times during Bingo games, there could be more than a dozen winners in a game. Of course, this led to monetary issues for the churches and halls having to pay the winning players.

Because of this, Lowe requested the assistance of a man named Carl Leffler. Carl was a professor of mathematics at Columbia College. Edwin S. Lowe asked Carl to create 6,000 Bingo cards that had non-repeating number groups.

This took some time and was very difficult for Carl to do, but he did indeed do it! The creation of these 6,000 cut back on the number of winners per game, which helped Bingo halls everywhere!
