Denton Arthur Cooley (born August 22, 1920) is an American heart surgeon famous for performing the first implantation of a total artificial heart. Cooley is also founder and surgeon in-chief of The Texas Heart Institute, chief of Cardiovascular Surgery at St. Luke's Episcopal Hospital, consultant in Cardiovascular Surgery at Texas Children's Hospital, and a clinical professor of Surgery at the University of Texas Medical School at Houston.

Cooley graduated in 1941 from the University of Texas, where he was a member of the Kappa Sigma fraternity, played on the basketball team, and majored in zoology. He became interested in surgery through several pre-med classes he attended in college and began his medical education at the University of Texas Medical Branch in Galveston. He completed his medical degree and his surgical training at the Johns Hopkins School of Medicine in Baltimore, Maryland, where he also completed his internship. At Johns Hopkins, he worked with Dr. Alfred Blalock and assisted in the first "Blue Baby" procedure to correct an infant's congenital heart defect.

Daniel Denton (c. 1626 – 1703) was an early American colonist. Denton led an expedition into the interior of northern New Jersey. He was one of the purchasers of what is known as the Elizabethtown Tract in 1664, in the area of (and surrounding) present day Elizabeth, New Jersey. In 1670 he wrote the first English-language description of the area.

Denton was born around 1626 in Yorkshire, England. He was the son of the Reverend Richard Denton, one of America's earliest Presbyterian ministers. Many Denton family genealogies claim Daniel's mother was Helen Windebank. In the 1640s he accompanied his father to Massachusetts, Connecticut, and eventually Long Island. In 1650 he was made town clerk of Hempstead, where his father was a pastor, and in 1656 he held the same position in the town of Jamaica. When his father relocated to Halifax, Nova Scotia (or Halifax,Yorks, England), Denton remained on Long Island, and in 1664 he became one of the grantees of a patent at Elizabethtown, New Jersey. In 1665 and 1666 he served as justice of the peace in New York. Around 1659, Denton married Abigail Stevenson, who bore three children, and from whom he was divorced in 1672. The two elder children, Daniel and Abigail, remained with their father, while the infant daughter, Mercy, accompanied her mother, who subsequently remarried. Denton left New York for England in 1670 (which may have occasioned his divorce), and there he evidently participated in settlement enterprises and possibly in the newly acquired (by the English) fur trade.
