Emmanuel Lobb (1594–1671), pseudonyms Joseph Simons or Simeon, was an English Jesuit and dramatist.
He is chiefly remembered for converting the future King James II to the Roman Catholic faith.
Born at Portsmouth, Lobb was at age of 11 sent to Portugal to learn the language for commerce, and there was converted to the Roman Catholic faith by Henry Floyd.
[1] Later sent on the English mission, Lobb was at one period rector of the College of St. Ignatius.
When residing in London in 1669 he was consulted by James, Duke of York, whom he subsequently reconciled to the Roman Catholic church, although the precise details of James' conversion are unknown, due to a highly effective Government "black-out".
