The book Radioactive: How Irène Curie and Lise Meitner Revolutionized Science and Changed the World, by Winifred Conkling has an adequately detailed summary of the personalities of Marie and Irène Curie, as well as Lise Meitner. Whilst all descriptions seem to indicate autistic traits of these physicists, Irène Curie seems to be autistic, as she was the very preoccupied with her work (hyperfixation), was considered rude for speaking directly, and preferred math and science work even on holiday. Whilst this is all speculation on my behalf, it seems to me as though these recounts suggest Irène Curie had a greater number of autistic traits than the typical person at the minimum.
