Deepak Chopra (born October 22, 1946) is an American author, public speaker, alternative medicine advocate, and a prominent figure in the New Age movement. Through his books and videos, he has become one of the best-known and wealthiest figures in alternative medicine. Chopra studied medicine in India before emigrating to the United States in 1970 where he completed residencies in internal medicine and endocrinology. As a licensed physician, he became chief of staff at the New England Memorial Hospital (NEMH) in 1980.

Chopra was born in New Delhi, India, to Krishan Lal Chopra (1919-2001) and Pushpa Chopra.  His paternal grandfather was a sergeant in the British Indian Army. His father was a prominent cardiologist, head of the department of medicine and cardiology at New Delhi's Moolchand Khairati Ram Hospital for over 25 years; he was also a lieutenant in the British army, serving as an army doctor at the front at Burma and acting as a medical adviser to Lord Mountbatten, viceroy of India. As of 2014 Chopra's younger brother, Sanjiv Chopra, is a professor of medicine at Harvard Medical School and on staff at Beth Israel Deaconess Medical Center.  Chopra completed his primary education at St. Columba's School in New Delhi and graduated from the All India Institute of Medical Sciences in 1969. He spent his first months as a doctor working in rural India, including, he writes, six months in a village where the lights went out whenever it rained. It was during his early career that he was drawn to study endocrinology, particularly neuroendocrinology, to find a biological basis for the influence of thoughts and emotions.  He married in India in 1970 before emigrating with his wife that year to the United States. The Indian government had banned its doctors from sitting the American Medical Association exam needed to practice in the USA, so Chopra had to travel to Sri Lanka to take it. After passing he arrived in the United States to take up a clinical internship at Muhlenberg Hospital in Plainfield, New Jersey, where doctors from overseas were being recruited to replace those serving in Vietnam.  Between 1971 and 1977 he completed residencies in internal medicine at the Lahey Clinic in Burlington, Massachusetts, the VA Medical Center, St Elizabeth's Medical Center and Beth Israel Deaconess Medical Center in Boston. He earned his license to practice medicine in the state of Massachusetts in 1973, becoming board certified in internal medicine, specializing in endocrinology.
