Not the best, but I’ll mention Harry Harrison, just because I want the Stainless Steel Rat TV series. No need to be loyal to the books, just a good space-thief-forced-into-being-a-space-cop series is all I need.
RAH, RAH, RAH!!! Robert A Heinlein. As a young adolescent I found I will fear no evil and then I went through the entire school library. Once finished there I turned to the city library then bookstores, both new and used. I learned of his non-de-plume and ran those to ground. In the 80s I was in the US Navy and rode fast attack submarines. We pulled into port somewhere in the Pacific and I trotted off to the facility that loaned test equipment and under the glass-top counter was the obituary for Mr Heinlein. Kinda took the wind outta my sails so to speak Haven’t thought about that in a very very long time.
