Thelma Ellen Wood (July 3, 1901 – December 10, 1970) was an American artist, specialising in the traditional fine line drawing technique known as Silverpoint.

[2] While in Paris, Wood frequented Berlin and was said to have enjoyed excessive alcohol consumption, and being involved in casual sexual relationships.

Wood became involved in an affair with a wealthy woman named Henriette Alice McCrea-Metcalf, leading to the end of her relationship with Barnes.

Wood was outraged, believing Barnes' portrayal was a misrepresentation, and claimed that the publication of the book ruined her life.

Wood's sketchbook from a trip to Berlin remains in the Barnes Papers at the University of Maryland, College Park.

[6][7] Wood's silverpoint drawings were exhibited at least once, at Milch Galleries in New York City in 1931 where Mary Fanton Roberts reviewed her work favorably.

[8] Around 1942 or 1943, her relationship with Metcalf had deteriorated to a breaking point due to Wood's unfaithful sexual activities and lack of any gainful employment.

Metcalf offered Wood money to move out of their shared house and effectively ended their sixteen-year relationship.
