Joslin's associates were chosen to expand his interests in foot salvage for the middle aged diabetic prone to peripheral vascular disease as well as group education for diabetics in the hospital setting. This later expanded to include the first nurse educator service and children's diabetic camps. His proteges, including Drs. Alexander Marble and Priscilla White, followed his mandate to investigate problems in diabetes and metabolism. Marble became Joslin's first research director, and White created the first "high risk" pregnancy clinic aimed at improving outcomes for infants and the insulin-dependent woman during pregnancy and at delivery.
