I am a German born, Jewish-American theoretical physicist, born in 1879, who developed the theory of relativity, and is best known for my equation E = mc². 
I once said, "Vegetarian food leaves a deep impression on our nature. If the whole world adopts vegetarianism, it can change the destiny of humankind."

I am a Jewish-American physicist, and radio astronomer, born in 1933, who accidentally co-discovered Cosmic Microwave Background Radiation when  working on a radio telescope at Bell Laboratories in 1964. 
I received the Nobel Prize for this discovery despite the fact that other scientists of the time had predicted the existence of CMB Radiation, and were building low-frequency telescopes to find it!

I am a female, American astronomer, born in 1868, who discovered the relation between the luminosity and period of Cepheid variable stars in 1908. 
I received little recognition in my time, but my discovery allowed astronomers to measure the distance between Earth and distant galaxies!

I am a female, German astronomer, born in 1847, who discovered several comets and was the first female given the title "astronomer." 
I survived typhus as a ten year old which stunted my growth! I never grew to be over four feet tall! My older brother and uncle are famous astronomers, too!

I am a Jewish-American astronomer, cosmologist, astrophysicist, and author, born in 1934, who is best known for my work in exobiology, and for making science accessible to the general public with my television series, Cosmos. 
I assembled the first physical messages sent into space upon the Voyager space probe, which are traveling through interstellar space today!

I am an English-born 
theoretical astrophysicist, and cosmologist, born in 1942. I was diagnosed with ALS in 1963 and was told I had only a few years to live. I am best known for my work on gravitational singularity theorems in the framework of general relativity.
I am a supporter of the many-worlds interpretation of quantum mechanics!
