Thomas Cottam was a 16th-century Jesuit missionary and Catholic priest from Lancashire. Born into a Protestant family, he studied at Oxford before converting to Catholicism in London. This spiritual shift led him to pursue the priesthood, eventually joining the Society of Jesus. While he had originally hoped to serve as a missionary in India, he instead returned to England to minister to Catholics. His mission resulted in his arrest and subsequent execution in London during the reign of Elizabeth I.
Life and mission

After earning his master's degree at Oxford, Cottam worked as a grammar school master in London. Following his conversion, he traveled to the continent to prepare for the priesthood. He joined the Jesuits in Rome in 1579, but illness forced him to recover in Lyons. During this time, he was identified by a spy, which led to his arrest upon arriving in Dover. Despite attempts to help him reach London safely, he eventually surrendered to the authorities.
Martyrdom
While imprisoned in the Marshalsea and later the Tower of London, Cottam endured significant torture, including the use of the rack. He was tried alongside Edmund Campion and received a death sentence in late 1581. His execution finally took place at Tyburn on May 30, 1582. He is recognized as a blessed martyr within the Catholic tradition.
