Harry Sears attended Boston Latin school and later Harvard College, graduating in 1893. He graduated from Harvard Medical School in 1896 and eventually took up a practice on the North Shore of Massachusetts. He served as a physician in the Spanish-American War, reaching the rank of lieutenant-colonel. He was then on the staff of Beverly Hospital for 20 years, serving as medical examiner for the Beverly region. In 1920 Sears suffered a nervous breakdown and was hospitalized for several months. His wife then sustained a serious illness, and on the day of her surgery, Harry Sears went to his medical office and took his own life by shooting himself through the heart.
