One of the most lasting pleasures you can experience is the feeling that comes over you when you genuinely forgive an enemy- whether he knows it or not. O. A. Battista (June 20, 1917 – October 3, 1995), also frequently referred to as O.A. Battista, was a Canadian-American chemist and author. A devout Catholic, he was notable in his writing for not shying away from advertising his religious beliefs as well as his scientific ones.
A nice page with more of his quotes is here.
There might be more pictures of him on the web, but my Spanish is not that good and the sites that came up might have been him but much older, so unfortunately you will have to make do with one photograph of O.A. Battlisa.
