The family moved to affluent Bloomfield Hills, Michigan, around 1953. In 1953, Lenore suffered another health crisis when a blood transfusion of the wrong type put her life in danger, but she recovered. In 1954, George was named president and chairman of American Motors Corporation. During this time a bad attack of bursitis left her with no movement in her left arm for five years, and the rest of the family took up her chores. The couple spent summers at a cottage on the Canadian shore of Lake Huron. A slipped disk suffered there gave her further trouble, and that and the bursitis caused her to switch from golf to swimming as her main exercise.
