Wang Zhenyi

[susanreads]

She is an astronomer, June:

Wang Zhenyi

1768-1797

Chinese astronomer who studied lunar eclipses using models she constructed in the garden of her home. Despite her short life, Wang Zhenyi was extremely productive. She wrote twelve books on astronomy and mathematics; among them she mentions “Some observations of the forms and figures” dedicated to the positions of the stars in the sky. She described the heavens and Earth’s place in it. She also recompiled data about the weather in order to prevent and combat the draughts and floods that devastated the region.

Conscious of being a privileged woman, she believed that knowledge should reach men and women equally.

In 1994, the International Astronomical Union named a crater on Venus after her.

On the calendar there's also an artist's impression of Wang Zhenyi with a diagram of a lunar eclipse, a reference to another of her books, The Interpretation of the Eclipse of the Moon.

Most of the search results for this name are other people, especially a modern male scientist. The Biographical Dictionary of Women in Science has an article on her which I found on Bookrags. Correction to the calendar: She spent years gathering data on the heavenly bodies and the clouds. The data gathered from her attempts to measure atmospheric humidity were used for weather forecasting and, purportedly, could predict floods and droughts.
