He graduated at Harvard in 1721, and was instrumental in the Smallpox inoculation controversy of that year, speaking out in favour of inoculation. He travelled to London and met with Thomas Hollis, who wished to endow a Chair at Harvard College for him. He later fell out with him, over his lack of financial prudence. However, back in Boston, Greenwood was eventually appointed to the new Hollis Chair in 1727. During his tenure, he wrote anonymously the first natively-published American book on mathematics – the Greenwood Book, published in 1729. This book made the first published statement of the short scale value for billion in the United States, which eventually became the value used in most English-speaking countries.[3] He was removed from the Chair for intemperance (drunkenness) in 1737. Unable to support his family, he joined the Royal Navy as a chaplain - HMS Rose in 1742, and later HMS Aldborough in 1744. He was released from service in Charleston, South Carolina, on 22 May 1745, and drank himself to death a few months later on 22 October 1745.

He married Sara Shrimpton Clarke, daughter of Dr John Clarke, on 31 July 1729, and had five children, of whom the eldest, Isaac, became a noted dentist.[1]
