Jeffrey Mace

Jeffrey Solomon Mace, also known as the Patriot and Captain America, is a superhero appearing in American comic books published by Marvel Comics. The character was created during the 1940s, a period fans and historians call the Golden Age of Comic Books. As the Patriot, he first appeared in Human Torch Comics #4 (March 1941; mis-numbered #3 on cover), published by Marvel's 1940s precursor, Timely Comics. In 1976, Marvel revealed via retroactive continuity that Mace had become the third Captain America some time after his World War II era adventures. He is also the uncle-by-marriage of Thunderbolt Ross. The character was adapted into the Marvel Cinematic Universe TV series Agents of S.H.I.E.L.D., portrayed by Jason O'Mara.
