YMMV but I found Masterminds of Programming quite a worthy read. It is an interview based book and talks to the creators of a variety programming languages, including such 'obscure' ones as Forth, APL and Eiffel. I am interested in programming languages in a meta way, and even dabble around designing a couple, so it was inspirational to me, also quite an eye opener.
