William Humphrys (c. 1794 – 21 January 1865) was an engraver of pictures, book illustrations and postage stamps.
At an early age he moved to the United States where he studied engraving techniques under George Murray in Philadelphia.
Two years later he moved to Dublin to engrave "The Reading Magdalene" for the Royal Irish Art Union.
[4] In a report in The New York Times of 18 June 1922[5] A Hatfield Jr is quoted from his book "There are indications which lead me to the opinion that the engraver was no other than that gifted British artist William Humphrys .... in his obituary notice in The Art Journal (1865) it is stated that he engraved the portrait of Washington for United States stamps.
At that time Perkins Bacon had the contract to produce stamps for the United Kingdom and for the many British possessions around the world.
