Summary
This episode explores the London Necropolis Railway, a 19th-century transit system built to move bodies to a new cemetery after London ran out of grave space, featuring class and religious segregation for the dead. The second story details Werner Forssmann’s daring 1929 self-experiment, where he inserted a catheter into his own heart to pioneer cardiac diagnostics, a breakthrough that eventually earned him the Nobel Prize.
