Who invented blood bank and when?

dr. charles richard drew invented the blood bank in 1937

I'm Sorry, but it was NOT Dr. Charles Drew. Dr. Charles Drew is credited with building a lot of blood banks during early WWII which began in 1939, not inventing them. Sergei Sergeevich Yudin built the world's first blood bank in March 23, 1930.

(I'm a proud descendant, which is why I know for sure <(-_-)> ). That, and there are also online sources to verify.
