Chief Rabbi Aaron Uri Phoebus Hart (1670, Breslau - 1756, London) was, from 1704 until his death, the first Chief Rabbi of Britain and the Rabbi of the Great Synagogue.
He was the son of Hartwig Moses Hart of Hamburg, a resident of a prosperous Jewish city. After studying at a yeshiva in Poland, he married the daughter of R. Samuel ben Phoebus of Furth, author of the Eben haEzer commentary. In 1692, he was appointed rabbi of the first German Jewish synagogue in London.
In 1707, he published Urim ve-Tummim, the first Hebrew book printed and published in London.
Rabbi Hart's portrait hangs in the National Portrait Gallery in London.
