Although a character in his own right, perhaps his most important contribution to the MCU, was being the father of Tony Stark (Iron Man).
Just as like his son is, Howard was a genius inventor and playboy, who founded Stark Industries, as depicted in The First Avenger. He later co-founded S.H.I.E.L.D., as seen in Iron Man 2 and the aforementioned Marvel One-Shot.
In Captain America: Civil War, his and Maria Stark's death were revealed to be done by the brainwashed Bucky Barnes (Winter Soldier), which happened on December 16, 1991. Before that, it seemed to be the day after, although this seemed to be the date the news covered it, although a deleted scene from The Avengers actually gave the date of December 17, 1991 as his death, which was read by Steve Rogers (Captain America) on his file.
The Agent Carter Marvel One-Shot film had Howard start up S.H.I.E.L.D. in 1946, but the following Agent Carter TV series is also set between 1946-1947 and with no mention of the status of S.H.I.E.L.D., would push this date a few years further to at least 1949.
