Mr. Kalmann grew up one of four boys in the Netherlands. Mr. Kalmann jumped in and pulled two of the men to shore. Initially, Ms. Jacobus’s friends warned her that it was too dangerous and pointed out that she would be working more hours as a lifeguard than she did as a social worker. But like Mr. Kalmann, she felt a deeper calling. She is the daughter of a Lutheran pastor and grew up doing volunteer work before entering social work.
