[1] At a young age he relocated with his family to Pittsburgh, Pennsylvania,[1] and after graduating high school in 1940, moved to Washington, D.C.[1] Prevented by a heart condition from being drafted into the U.S. military during World War II, he began studying art at Cooper Union, in New York City.

[9] In later years, he independently teamed with inker Jon D'Agostino under the pseudonym Matt Bakerino[citation needed] at Charlton Comics.

"[12] The character Phantom Lady, created by Arthur Peddy, had originated in 1941 as a Quality Comics feature supplied by the Iger Studio.

[13] When psychiatrist Frederick Wertham claimed comics had ill effects on a child's psychological development, he used Baker's Phantom Lady #17 as a key sample.

[14] His other artwork for comic books includes the light-humor military title Canteen Kate, for which Baker drew all 22 installments,[15] as well as stories in the suspense anthology Tales of The Mysterious Traveler; the comedic-adventure feature "Sky Girl" in Fiction House's Jumbo Comics, with originals and later reprints running from #69-139 (November 1944 – December 1952); the jungle adventure "Tiger Girl"; "Flamingo", "South Sea Girl", "Glory Forbes", "Kayo Kirby"; and "Risks Unlimited".

[16] He is the generally credited but unconfirmed artist for Fox's Rulah, Jungle Goddess #17–27 (Aug. 1948 – June 1949, the title's complete run after having taken over the numbering of the defunct Zoot Comics).

"[19] The Tarzan-like jungle hero Voodah, drawn by Baker and scripted by an unknown writer, debuted in the publisher McCombs' Crown Comics #3 (cover-date Fall 1945, on-sale date Sept. 19, 1945).

[20] As the Grand Comics Database states, based on art credits from "The Matt Baker Checklist" by Alberto Becattini and Jim Vadeboncoeur Jr. in Matt Baker: The Art of Glamour (cited under References), "Voodah is colored like a native African in this comic, but after this issue he is colored like a Caucasian."

[21] In the late fifties, he branched out into illustration work, for instance for the 16-page illustrated condensation he did of Howard J. Lewis' The Complete Guide to Better Bowling (1956, Maco Magazine Corporation) for the General Motors' Information Rack Service number 1R-58-46 [22] and the early issues of the St. John detective pulp digest Manhunt [23] His last known confirmed work is the six-page "I Gave Up the Man I Love!"
