Michael Pupin Idvorsky and father Vasa Zivkovic
  There is often a bond between two great men of a society at the time when one is at the peak of his life and the other at its beginning. The great Serbian 19th century poet, clergyman and educator father Vasa Zivkovic, interceding in favour of his student Mihajlo Pupin, significantly influenced the conditions necessary for Pupin`s development into the person he later became. Mihajlo Pupin was certainly not the only student to benefit from father Vasa Zivkovic advice and material support. However their relationship is a perfect example of an acclaimed person successfully influencing a person yet to win acclaim.
