I still remember asking my high school guidance teacher for permission to take a second year of algebra instead of a fifth year of Latin. She looked down her nose at me and sneered, 'What lady would take mathematics instead of Latin?'

It was probably my parents who inspired me most. My father was a scientist and answered my scientific questions, while my mother took me on walks and showed me birds and plants. She also took me out at night and showed me the constellations and the aurora.

In 1956, I received an invitation to a dedication of an observatory in the Soviet Union, in Soviet Armenia, as a guest of the Soviet Academy of Sciences.

I started out, as most astronomers do, with a university job. But in my generation, women weren't very welcome at universities, and so I found a job in the government. And the government was appreciably more welcoming.

One of the reasons I like working with schools is to try to convince women that they can be scientists and that science can be fun.

Certainly by the time I was in seventh grade, I knew I had to have a long education if I wanted to become an astronomer, but I figured I'd try it, and if I didn't get far enough, I could always end up teaching in high school or math or physics.
