. He received his Bachelor's and Medical degrees from Harvard. While working at the Bellevue hospital in New York, he was awarded a fellowship to London to continue his studies in medicine.

During the Second World War, Harken served in the U.S. Army Medical Corps in London as a surgeon. To treat his patients, he found a way to take out shrapnel safely from the heart by cutting into the wall of a beating heart, then inserting a finger to locate and remove the shrapnel. With this method, he became the first person to have repeated success in heart operation after removing shrapnel from the hearts of 130 soldiers during the war without a single fatality.
