• Resumen

  • The long-sought and elusive Element 87 was finally discovered by Marguerite Perey, the first woman to be elected to the French Academy of Sciences. Following this distinction, which was early in her illustrious career, Perey's painstaking efforts—carrying out hundreds of fractional crystallizations and then quickly and skillfully analyzing each fraction—resulted in her discovery. Perey's work to discover Francium was intentional and laborious: the element was not discovered by accident, as has been reported by some.
