Katalin is the Hungarian form of Catherine — from the Greek katharos (pure). Member of the National Academy of Sciences (2022).
Subject of her memoir Breaking Through (2023).
Katalin does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Katalin reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
