Consider the men who invented the operational amplifier circa WWII. The op-amp was tremendously important to modern electronics and still is used today in all kinds of products. Wikipedia gives them almost no credit.

And this is the part that really disgusts me: Wikipedia also fails to mention Mr. Julie's treatment at the hands of John R. Ragazzini, dean of electrical engineering at Columbia. Because Ragazzini committed one of the most notorious acts of intellectual theft of all time on Julie.

When Julie's work on the amplifiers was almost completed, a short while before Philbrick placed his contract, Ragazzini hired two college professors, Robert Randall and Frederick Russell. To Ragazzini's displeasure, Julie taught them about his design. Ragazzini didn't particularly like Julie, Julie reported. He accused him of intellectual arrogance, deprived him of credit for his design and ended his draft deferment.
But by god, Ragazzini won awards. And so his article is longer than the articles of those actual pioneers.
