It’s the HistoryExtra podcast’s 15th birthday, and to celebrate, we’ve asked 15 historians to nominate a figure from history they think deserves their ‘15 minutes of fame’. In this episode, Dr Hannah Greig nominates 18th-century printseller Hannah Humphrey. Speaking with Elinor Evans, she reveals how Humphrey worked with leading caricature artist James Gillray and built a successful business in her own right.
