Who Designed Captain America's Shield?

In the comics, Captain America's circular shield was designed by Myron Maclain. Surprisingly, we don't learn this until Avengers #66 (May 1969).

In Captain America: The First Avenger (2011), we learn that Howard Stark - Iron Man's father - was a key member of the Super Soldier Program and designed the shield himself.

In Captain America: White #3 (2015), however, Cap mentions he believes Howard Stark invented it.

This is an interesting canon immigrant because it's not concrete. We don't see Howard Stark working on it; it doesn't even say for sure that he did invent it. All we know is that Steve heard he invented it. This allows writers going forward to keep it Myron Maclain or change it to Howard Stark and pretty much be right either way.
