I always like to point out to people that there are many famous atheists in every profession. To demonstrate that fact, I have prepared a short list of classical composers, many of whom were obliged to create religious music simply to pay their bills, yet they were sincere atheists. Why are there so many atheist composers?
You might expect scientists to be atheists because they haven’t found any proof that there is a God. However, I think many “creative types” may be predisposed to atheism as well. This is pure speculation on my part (or possibly the ramblings of an idiot savant). I think the creative process allows the mind to explore all possibilities – including the denial of the existence of a supernatural being. Once accomplished, that denial sure eliminates a ton of spiritual baggage.
I have included several modern atheist composers as well, just to see if you can find them in the list.
THE LIST:
Béla Bartók
Hector Berlioz
Georges Bizet
Johannes Brahms

(yes, he was a serious composer of modern classical music)
Steelman The Humanist 
Love to tell people that I am an atheist, and see the shock on some of their faces.
I knew about most of the composers, and like being in such good company.
As you know, FFRF always has the list of atheist/humanists,etc. in their newspaper.
People would be surprised to see how many of those who have made great contributions to society are non believers.
So happy to be free of such nonsense!
