Nope, don't know who he is, but it's not the US assisting Iran with their nuke program.
He was Iranian Shah, and big friend of USA. It was USA, who assisted in building research center, supplied equipment and enriched uranium for experiments. Germany begun building of Busher nuclear power station, because West persuaded Pekhlevi to use nuke energy instead of oil and gas. At that time there where no Islamic states led by mullahs, nobody even can imagine about such thing. And nobody would believe in crushing of USSR and Warsaw Treaty.
