H. Newell Martin

Henry Newell Martin, FRS (1 July 1848 – 27 October 1896) was a British physiologist.

He was born in Newry, County Down, the son of Henry Martin, a Congregational minister, and educated at the University of London and Christ's College, Cambridge. In 1876 he was appointed to the first professorship of physiology at Johns Hopkins University in the United States. He co-wrote with Thomas Huxley Practical instruction in elementary biology. He collaborated with George Nuttall. He developed the first isolated mammalian heart lung preparation (first described in 1881) which Starling later used to great effect. Martin's own scientific career was curtailed around 1893 due to alcoholism.

He was elected a Fellow of the Royal Society in 1885, having delivered their Croonian Lecture in 1883 on "The Direct Influence of Gradual Variations of Temperature upon the Rate of Beat of the Dog's Heart".

In 1879, he married Hetty Cary, widow of Confederate General John Pegram. He died in Burley-in-Wharfedale, Yorkshire.
