Henri-Sanson enjoyed working up a crowd before performing executions. He attracted record numbers and was one of the most efficient public executioners in Paris. He once executed 300 people during 3 days of the Reign of Terror and was asked to slow down because residents of a nearby street were complaining that the stench of blood would drive house prices down. He was so skilled that he could guillotine 12 people under 13 minutes. He famously made Marie Antoinette one of those people in front of 200,000 cheering fans.
