Oswald Tesimond

Oswald Tesimond (1563 – 23 August 1636) was a Jesuit born in either Northumberland or York who, while not a direct conspirator, had some involvement in the Gunpowder Plot.

He was educated in York, in the Royal school of William and Mary in the Horse Fayre, which cost no money to attend. Guy Fawkes. Edward Oldcorne and brothers Christopher and John Wright were among Tesimond's classmates, all of whom would become involved in the Gunpowder Plot. Tesimond was entered into the Society of Jesus in 1584, but not before he left the English College in Rome, into which he had been first initiated; to leave the College and come into the Society, he required special permission from the cardinal protector (who was Giovanni Morone, at the time), which he successfully obtained.

Later, among other things, Tesimond studied theology in Messina, where he afterwards taught philosophy. Sometime before he left on the English mission, during November 1587, he was ordained, but the exact date is not known. As part of this mission, he arrived at Gravesend on 9 March 1598. For eight years he then worked with Edward Oldcorne in Worcestershire and Warwickshire before he was professed of the Jesuits' four vows on 28 October 1603.

Later, he became somewhat involved in the Gunpowder Plot, after receiving knowledge related to the nature of the plan. He concealed his intelligence, despite his faith. He effectively documented his experiences in a narrative which he sometime after wrote.

He lived the later part of his life in various places, including Saint-Omer and Naples. He died on 23 August 1636, at 73 years of age.
