In 1945, Robert Sherman invented the modern portable, in-window air conditioner (Patent # 2,433,960 granted January 6, 1948). It was subsequently "appropriated" by a large manufacturer who made hundreds of millions of dollars on it. Sherman did not have the resources to fight the big corporation in court (they reportedly promised to "break him" if he tried) and thus never received a dime. He died in 1962. Recognition of his contribution to heating/air conditioning is long overdue.
