Charles Foster or Donald Knuth both come to mind. Multiple studies put the religious attendance of scientists at around 15 to 20% with belief in a high power or god at around 40 to 50%.
Georges Lemaître: Priest & Scientist; Father of the Big Bang Theory; He was the first to derive what is now known as Hubble's law and made the first estimation of what is now called the Hubble constant, which he published in 1927, two years before Hubble's article. https://en.wikipedia.org/wiki/Georges_Lemaitre
Be careful using those lists to show that people on them are "religious"; the articles' notes themselves quote laureate Orhan Pamuk (on the list of Muslim laureates) as saying "I do not believe in a personal connection to God" and James Gleick as saying that laureate Richard Feynman (on the list of Jewish laureates) was "distinctly uninterested in either the faith or sociology of Judaism".
You can also follow random Wikipedia article links and find, for example, laureate Joseph Rotblat saying "I am not a particularly religious person, and this is the reason for my agnosticism".
I think he meant today. Aren't like >90% of scientists in the hard sciences atheists or at least non-religious? Of course there are thousands of counterexamples, but by "hard to find" I think he meant if you went down to the local uni you might not find anyone at all.
Most scientists in the U.S. are nonreligious, or less religious than the general population around them, but the original commenter said you would be "very hard pressed" to find a counterexample who's a reputable scientist. Surely "very hard pressed" should mean it's actually difficult to do so.
Also, I wonder what a very religious scientist would answer.
