The "dip" on the windshield shape was a Howard Darrin design feature that was first seen in the 1951 Kaisers (check the window line at the top; the dip is at the center bar area of the 2-piece windshield). Henry's wife Bess died in early calendar 1951 and he married Ale soon afterwards (Ale was one of Bess' nurses in her last weeks). Henry had nothing to do with it other than he was one of the Executive Committee members who approved the design for production in 1948 when the styling competition for the 1950 models (which were pushed out to become early release 1951 model year cars) took place.
However, you can thank Ale for the Kaiser-Darrin. Henry was pitched the car by Darrin. He wasn't that keen on putting resources into a sports car, but Ale Henry she would like to have one and that others probably would want one too.
