We all know about Albert Einstein, the founder of the theory of relativity but how about the person who taught him and showed him the way to a bright scientific journey which would change the world? That was his teacher, Konstantinos Karathodoris. During one of his last pubic appearance Albert Einstein said, “You ask me to answer to all sorts of questions, but noone has ever wanted to know who was my teacher, who showed me the way to the higher mathematical science, thought and research. I simply say that my teacher was the unrivalled Greek Konstantinos Karatheodoris, to who we owe everything…” Indeed, it was a Greek from Thrace. He has not only been in touch with Einstein but has also hepled him to complete the theory of relativity.
