Max Bennett. He's not famous famous but he's well known enough in the jazz scene. He played with Frank Sinatra, Dizzie Gillespie, and recorded on countless studio sessions. I knew him personally and I think was his last student before he passed. Some people closer to him than me told me one of the last things he said was "I need to give jcabral9 his lesson" and it makes me tear up whenever I think about it. I was too young to understand most of his concepts–I wish I could know him as an adult and professional musician myself.
Reminds me of the time my old roommate was outsmarted by his cat.
He was sitting on the piano bench after some practice and I and another friend were sitting on the couch. We were all having a light conversation in the evening but his cat had all his comfy spots taken. He jumped up on the kitchen counter in protest–a spot he's not meant to be–and my roommate went over to shoo him down. After he sat back down on the piano bench, I saw a lightbulb go off in the little cat's brain. He hopped up on the counter again to test his hypothesis, and sure enough, my roommate went over to shoo him down. After the third time jumping up on the counter, the cat rushed over to the piano bench and immediately laid down. My roommate, being the sweet man he was, sat back down next to him on the little corner of the bench as to not disturb him :)
It was one of the most genius things I've ever seen an animal do.
