Concerning the Einstein 1994 Turkish stamp. I do not see it listed in the Scott catalogue. Is it a Cinderella?

Not a cinderella. Michel # 3018 (Scott # 2598?)

This may be the earliest Albert Einstein stamp (FDC).

I bought it right now on WOPA

I don't have any pictures to post here, unfortunately, but Einstein has long been one of my favorite human beings, for a lot of reasons.

I find it a bit amusing (and also a bit troubling) to see stamps such as the ones from Aitutaki on p. 1 of this thread that show him in association with nuclear weapons. Aside from urging Roosevelt to look into the development of nukes (mostly because he was worried Nazi Germany was already doing so), he had nothing to do with the Manhattan Project or nuclear weapons in general. His famous E=MC^2 equation gives the formula for how much energy will be released in an explosion, but otherwise didn't by itself enable the construction of nuclear weapons. He really shouldn't be associated with nukes, other than in a tangential way.

Somewhat less of an issue, but still potentially misleading, is the depiction of atoms in association with Einstein. Albert did make contributions to quantum theory ("the realm of the very small"), but others did far more than he to flesh this out. He is mostly known for his theories of special and general relativity ("the realm of the very large") an area in which he eclipsed Isaac Newton, largely considered by other scientists to be the greatest scientist who ever lived.

(Side note - as I write this on 12/24/22 in the USA - it's actually 12/25 in the UK. Isaac Newton was born on 12/25/1642, so happy 380th birthday, Isaac! Yes, I know they used a different calendar at the time, so this might not be technically correct today, but I'm going to wish him a happy birthday, anyway.)

The first Israeli stamp shows Einstein (and probably, the first in the world), issued on January 3, 1956. It posted earlier on FDC. Here it is with tab:
