Madame Tussaud's waxwork

A London museum exhibiting lifelike wax effigies of famous people. A native of Switzerland, Madame Tussaud learned modeling in Paris, and started a museum exhibiting figures of famous and infamous people. Bradley (48) claims that she was compelled to make wax casts of the heads of victims of the guillotine. She moved her exhibit to London in 1802, one hopes without those replicated heads.
