The Gresham Professorships are a series of academic positions established in 1597 in London, England. They were created to promote the study and understanding of various subjects, including mathematics, astronomy, and music. The professorships are named after Sir Thomas Gresham, a financier and founder of the Gresham College, where these positions are based. Each Gresham Professor delivers free public lectures, making knowledge accessible to everyone. The professorships aim to engage the public in intellectual discussions and encourage lifelong learning. They continue to play a significant role in the educational landscape of London today.
