Sarah Rachel Russell or Leverson or Levison, best known as Madame Rachel (c.1814 – 12 October 1880), was a British criminal and con artist in Victorian-era London during the late 19th century. She operated a prominent beauty salon from which she sold fabulous preparations, such as her magnetic rock water dew from the Sahara Desert. She personally guaranteed her clientele everlasting youth as a result of the use of these products, which would later be revealed as consisting of water and bran. She would later become well known for blackmailing many wives of London's upper class.
