E. Dorrit Hoffleit, an astronomer who studied the features of stars visible to the naked eye, edited a standard reference on them and was probably the oldest working scientist in her field, died on April 9 at her home in New Haven. She was 100.
Dorrit Hoffleit sits near the window of her New Haven apartment, feeling every bit of her 99 years, 10 months, and five days. She is weak. She can no longer make the short walk to the Yale University astronomy department. She can't hear very well, and she now needs a caretaker with her day and night. Hoffleit, a senior research astronomer emeritus at Yale, is considered the oldest active female astronomer and perhaps the oldest active astronomer of any gender.
