Emmet was born in New Rochelle, New York to William Jenkins Emmet and Julia Colt Pierson. He is the great-grandson of Thomas Addis Emmet, a lawyer, who was an elder brother of executed Irish nationalist Robert Emmet. His father's parents were Robert Emmet and Rosina Hubley. His mother's parents were Josiah G. Pierson and Julia Colt.
His sisters included noted portrait artists Rosina Emmet Sherwood, Lydia Field Emmet and Jane Emmet de Glehn.[1]
In addition his brothers included, C. Temple Emmet, an attorney and sportsman who was a graduate of the Yale Forest School Class of 1902; William LeRoy Emmet, a graduate of the United States Naval Academy, Class of 1881; Devereux Emmet, who became a prominent golf course architect; and Richard Stockton Emmet.[2] His uncle, John Emmet, attended West Point from 1814 to 1817.

He graduated from the United States Naval Academy in 1881. He joined the Edison General Electric Company in 1891. Three years later, after a merger, he became employee of General Electric Company (GE). Emmet was a leading advocate of the electrical propulsion of ships from turbines. His systems were first used in American ships during World War I.[3] He also developed the mercury vapour turbine system for electric power production.
Emmet was elected to the American Philosophical Society in 1898.[4] He received the AIEE Edison Medal in 1919 For inventions and developments of electrical apparatus and primo movers. He received the Elliott Cresson Medal of the Franklin Institute in 1920 and was elected to the National Academy of Sciences in 1921.[5] Emmet worked at GE into his 70s and held 122 patents.[6]
