Missy, this is Wu Da You, a well known Chinese physicist in China. He was the teacher of Yang an
d Lee and was very influencial in Taiwan during the late 70s and early 80s.  

The other picture is Wu Jian Xiong, another well known Chinese physicist. She taught at Columbia
 University for many years and was one of the best experimental physicist in the world. Her most
 famous work was the experiement she carried out at NIST to prove the broen parity theory by Yan
g and Lee.  

Hope this helps.
