🇺🇸 William Maillis

William Maillis was born on September 19, 2008, in suburban Pittsburgh to Peter Maillis, a Greek Orthodox priest, and Nancy Maillis, a homemaker. The family was deeply religious; the household was, by all accounts, both warm and intellectually demanding. William was reading at two. He was doing multiplication at three. He was, by four, asking questions about astrophysics that his parents could not answer.

He was tested at six and returned a verified IQ in the 180 range. The number is, on the standard instruments, near the ceiling. By seven, he had completed high-school coursework. By eight, he was sitting in on community-college lectures. By nine, he was enrolled as a degree-seeking undergraduate at Saint Petersburg College in Florida — the family having relocated for academic reasons.

The press, predictably, descended. CBS, NBC, and Fox News ran segments. Greek and Greek-American outlets followed extensively. Religious outlets — particularly in the Orthodox and Catholic press — gave the story unusually warm coverage because of William's stated theological ambitions. His father, Peter, did not steer the family toward the religious press; the religious press came to him.

What separates William from many other American math-and-science prodigies of his generation is the explicit framing he has given his work. He has said, in multiple interviews, that he wants to use astrophysics — specifically, to research the origin of the universe and the implications of cosmological constants — to support a scientific case for the existence of God. The argument is not novel in philosophy of religion; fine-tuning arguments are well established. The unusual element is the seriousness with which a child has pursued the academic credential to make the argument professionally.

He has progressed through Bachelor's, Master's, and into doctoral-level work in astrophysics, all while a teenager. He has spoken at religious and educational conferences. He has been featured on Greek television. He has been profiled in The Atlantic. The question of whether his theological ambition will survive the standard sociological pressures of academic scientific training — pressures that have, historically, produced many former-religious scientists and very few formerly-secular scientists turning religious — is a part of his story that remains, in 2026, open.

What William Maillis demonstrates, in addition to his cognitive capability, is the existence of a contemporary American religious-prodigy archetype that the secular prodigy literature has not adequately addressed. The Greek Orthodox community in particular has, for decades, produced gifted children whose families channelled the gifts toward theological and humanistic, not narrowly STEM, ends. William is doing both. The combination is unusual. It is also, in his case, productive.
