It’s the HistoryExtra podcast’s 15th birthday! To celebrate, we’ve asked 15 historians to nominate a figure from history they think deserves their ‘15 minutes of fame’. In this episode, Professor Jerry Brotton nominates Marie Tharp. Speaking with Dave Musgrove, he dives into the life of the pioneering geologist and ocean cartographer and explores her remarkable legacy. See acast.com/privacy for privacy and opt-out information.
