Jared Kaplan — Notable For: Co-founder of Anthropic; Johns Hopkins physics professor; co-author of neural scaling laws research

NoteThe source directly confirms all three components of the claim: (1) Co-founder of Anthropic is confirmed ('co-founder and chief science officer of Anthropic'); (2) Johns Hopkins physics professor is confirmed ('associate professor in the Johns Hopkins University Department of Physics & Astronomy'); (3) Co-author of neural scaling laws research is confirmed ('co-authored Scaling Laws for Neural Language Models (2020)' which is explicitly about neural language-model scaling laws). All facts are present and accurate in the Wikipedia source.
