Latest Updates
Update at: Sep 14, 2026Marguerite Perey (1909–1975)
French physicist who discovered the chemical element promethium (Pm, atomic number 61) in 1945 while working at the Curie Institute in Paris.
Biographical overview
- Born: 19 October 1909 in Villemomble, France.
- Education: Studied physics at the University of Paris (Sorbonne) and pursued radiochemical research in the mid-20th century.
- Career: Conducted pioneering work at the Curie Institute (Institut du Radium) in Paris, focusing on rare earths and radioactive processes.
Major contribution
Perey is best known for identifying a previously unknown radioactive product produced during the irradiation of neodymium. This led to the recognition of a new element, later named promethium (Pm), element 61. Promethium is a lanthanide with no stable isotopes and occurs only in trace amounts, making its isolation and characterization a notable achievement in nuclear chemistry and radiochemistry.
Discovery details
The discovery occurred in 1945 at the Curie Institute in Paris. Perey’s work involved chemical separation and careful analysis of radioactive products derived from neodymium irradiation. The element was named promethium after Prometheus, reflecting its elusive and energetic nature in the periodic table. The identification of promethium contributed to the broader understanding of the rare-earth series and nuclear chemistry.
Career and legacy
Marguerite Perey’s research helped advance the study of radioactive elements and their placement within the periodic table. Her achievements have been cited in scientific histories and museum exhibitions dealing with the history of nuclear chemistry and the discovery of new elements. Perey’s career also served as an inspiration for women pursuing careers in physics and chemistry during a period when female scientists faced significant barriers.
News and public mentions
As a historical figure, there are no contemporary personal news or active projects. However, Perey’s work is periodically featured in science history articles, museum exhibits, and educational resources discussing the discovery of promethium and the broader development of radiochemistry and the lanthanide series.
Public presence and social media
There are no official social media profiles for Marguerite Perey. References to her work appear in academic databases, institutional histories (such as the Curie Institute), and science-history materials. Contemporary audiences may encounter her name in retrospectives about the discovery of elements or profiles of notable women in science.
Notes for readers
For further information, consult reputable science history sources, scholarly articles on the discovery of promethium, and museum or university pages devoted to the Curie Institute and the history of nuclear chemistry.
