Thanks Jan.

I have read this Cv from wiki, however, I am confusing. I still told my students that Bradford was a woman (?). So, why a lot of people thing that he is a woman? I have found the article where he(she) was presented as Melanii (not Marion) Bradford. Sounds like a woman.

Marion can be both a man or a woman's name, probably leading to the confusion. In the original paper the author is Marion M. Bradford. 

I think this link would be helpful for your query.

Thank you all for your replay.
