Christmas Savings Club Carlisle Trust had the first public Christmas Saving Club and it was brought about by Landis. In December 1909, three men from the local shoe factory approached Landis with an idea. They asked if they could open a joint account under their names with the idea of making a growing account of small deposits from each of their weekly pay checks to be saved in a special place. Landis, as the bank treasurer, set up an account where they collected money from the fellow workers and deposited one cent the first week, adding a cent each deposit for the next fifty weeks, with the last weekly deposit amount being 50 cents in December. They then were going to withdraw the total amount collected over the previous twelve months and distribute proportionally among themselves in the first part of December. Landis took this idea a step further and published display advertisements in the local paper that his bank was forming a Christmas Savings Club. Starting in the first week of January 1910 club members were allowed to make weekly deposits of any amount until the week before Christmas. They would get paid three percent interest on their total amount saved before being distributed as an incentive to contribute something each week. Landis, treasurer of Carlisle Trust Company, had originated the world's first Christmas Savings Club. He
