I would say that philosopher Tom Regan has made a name for himself, except that he has made two names for himself in his writings about ethics.
My own introduction to Regan's work came because of my interest in G. E. Moore, the-turn-of-the-(last)-century British philosopher who famously argued that the ultimate "goods" -- those that cannot be justified by reference to any other good -- are the appreciation of experiences of beauty and the appreciation of relationships with other people. All other values, he argued, ultimately can be measured by their tendency to contribute to detract from those things. Moore's ideas were very influential for the slightly younger generation of his students who became known as the Bloomsbury Group. Regan's book Bloomsbury's Prophet is very illuminating concerning Moore's influence on Bloomsbury. As part of a program for Penn State faculty to integrate ethics issues into their teaching, I used Regan's book to help create a unit on Moore's aesthetics in my English classes about Bloomsbury.
