Pierre Curie's grandfather, Paul Curie (1799&ndash;1853), a doctor of medicine, was a committed Malthusian humanist and married Augustine Hofer, daughter of Jean Hofer and great-granddaughter of Jean-Henri Dollfus, great industrialists from Mulhouse in the second half of the 18th century and the first part of the 19th century.
Through this paternal grandmother, Pierre Curie is also a direct descendant of the Basel scientist and mathematician Jean Bernoulli (1667&ndash;1748), as is Pierre-Gilles de Gennes, winner of the 1991 Nobel Prize in Physics.
Pierre and Marie Curies daughter, Irène, and their son-in-law, Frédéric Joliot-Curie, were also physicists involved in the study of radioactivity, and each also received Nobel prizes for their work. The Curies other daughter, Ève, wrote a noted biography of her mother. She was the only member of the Curie family to not become a physicist.  Ève married Henry Richardson Labouisse Jr., who received a Nobel Peace Prize on behalf of Unicef in 1965. Pierre and Marie Curie's granddaughter, Hélène Langevin-Joliot, is a professor of nuclear physics at the University of Paris, and their grandson, Pierre Joliot, who was named after Pierre Curie, is a noted biochemist.
