My father. Who took up cooking in his middle age, and made some of the best dishes I've ever tasted. He taught me not only how to cook, but how to have fun in the kitchen and take delight from other's pleasure when they ate. My brother and I still make his recipes today. Professional muses? I have to say only recently, and it would be Tony Bourdain. In Les Halles, he drills into the reader over and over, the importance of a mis en place, even in the home. Before I read that, I was a scattered cook, although I'm organized in all other ways! Now, I gather my mise first, and I seldom have to run to the store for things I've forgotten.
