Jack Dalton played four years in the majors, having an excellent season with the 1914 Robins.
Per the SABR biography, he was coached in college at the University of Virginia by Tom Brown (presumably the long-time player Tom Brown), and after graduating played semi-pro ball in 1907-08. Doc White took an interest in him, and gave him the nickname "Jack". After his time in the majors and minors, he again played semi-pro ball.
For a number of years Jack Dalton was one of the few 20th Century major leaguers whose whereabouts or date of death were not known. Dalton disappeared from Emmitsburg, Maryland in the early summer of 1948 and never again made contact with any of his associates or relatives. At the time of his disappearance, he was a part-time preacher for the Columbia Primitive Baptist Church in Burtonsville, MD; he disappeared on July 4, 1948, a Sunday morning, leaving home to attend a church service, but never arrived there and was never heard from again. He was listed as a missing person by the state of Maryland. In 2012, researchers using death records newly opened to the public by the state of Pennsylvania determined that Dalton died of a heart ailment in Allegheny Memorial Hospital in Pittsburgh, PA on February 17, 1950.
