It should be noted that his dad converted to Russian Orthodoxy when Yakov was 15. It's not clear, however, whether Yakov himself was baptized. His older brother Zinovy was.Either way, it's pretty clear he was an atheist in his adulthood and will always remain a Jew for Russian anti-Semites. That it to say, Russians.
Zinovy (known as Zinovy Peshkov) was quite a character, too. A French general and diplomat, of all things.
