grades were sufficient for him to earn a three-year scholarship at Princeton University, where he enrolled as a premedical student in 1962. By the second year of his studies, MacDonald and Wells had separated. He soon resumed his romantic relationship with Colette then a freshman at Skidmore College in Saratoga Springs. He would later recollect Colette had grown into a shy young woman with a "slight fear of the world in general" who would rely on his own self-confidence. MacDonald found her timidity touching, and gradually viewed himself as her protector in addition to her boyfriend. The two regularly exchanged letters, and he would frequently hitchhike to Skidmore College to be in her company at weekends. Although MacDonald was dating other women at the time, he resolved to marry Colette upon learning she was pregnant with his child in August 1963. She in turn left college to raise their child. With the consent of Colette's family, the two married on September 14 in New York City. One hundred people attended the service, with the reception held at the Fifth Avenue Hotel. The couple then honeymooned at Cape Cod. Their first daughter, Kimberley Kathryn, was born on April 18, 1964. Medical school Upon completion of his undergraduate degree at Princeton, MacDonald briefly worked as a construction supervisor before he moved with his wife and child to Chicago in the summer of 1965, where he had been accepted at Northwestern University Medical School. The couple moved into a small one-bedroom apartment, with Colette committed to maintaining the household and raising their daughter as MacDonald focused on his studies, while also working a series of part-time jobs to assist with family finances. The following year, the family relocated to a middle-class neighborhood. Their second child, Kristen Jean, was born on May 8, 1967. Shortly after MacDonald graduated from medical school in 1968, he and his family relocated to Bergenfield, New Jersey as he completed a one-year internship at the Columbia Presbyterian Medical Center in New York, specializing in thoracic surgery. MacDonald later described his internship year as "a horrendous year" for both himself and Colette, adding he frequently worked 36 hours with only 12 hours at home. Consequently, when at home, he was frequently exhausted and had limited interaction with his wife and daughters. At the completion of his internship, MacDonald and Colette vacationed in Aruba before MacDonald joined the Army. U.S. Army
