After noticing no page existed, I made my first Wikipedia page for Frank Walker Caldwell an American Propeller engineer and designer. A great picture of him being congratulated by President Roosevelt for winning the 1933 Collier Trophy from the Smithsonian included in the new page. Chief engineer Frank Caldwell's design for a hydraulic two-position, controllable-pitch, or hydro-controllable, propeller that patented in 1929 saved the Hamilton Standard Propeller company. I'm an aviation fan and I noticed that Frank Caldwell winning the 1933 trophy more than merits a page. So this is my first page, thanks for any feedback. I need to work on my references etc. Might you have additional info? Thank you so much in advance. Peter Schulz
