The son of a successful businessman, Jonas grew up in privilege and wealth, but was troubled about the advantages he had in comparison with others. He grew dismayed at the world. Pondering what he could do to bring a measure of stability and peace to the world, he reasoned that hope rested in the youth of the world and he began to consider what might encourage, stimulate and motivate them. He got the idea to start a camp, one that "is interested not merely in the boy, but in the man the boy will become." He set up a foundation, naming it after his father; the foundation runs the camp. For decades, Jonas personally interviewed many prospective campers and he was fondly called by all by his nickname, "Freddie."
