What was the title of Marie Curie's 1923 biography of her husband?

Marie Curie’s 1923 biography of her husband was titled Pierre Curie.

The book was Marie’s account of the life and work of the physicist with whom she collaborated closely. Pierre Curie was not only her husband but also her scientific partner in the pioneering investigation of radioactivity. Together, they studied pitchblende and identified the elements polonium and radium.

Marie wrote the biography years after Pierre died in a traffic accident in Paris in 1906. It combined personal remembrance with a description of his scientific character and achievements. The title is straightforward, which can make the question easy to confuse with titles associated with Marie’s own life or later popular biographies.

Pierre and Marie had shared the 1903 Nobel Prize in Physics with Henri Becquerel. Marie later won the 1911 Nobel Prize in Chemistry independently for her work on polonium, radium, and the isolation of radium. Her biography therefore also serves as a record of the scientific partnership behind one of the era’s most important discoveries.
