Check back from time-to-time as we will be updating the timeline with information as we find out more details.


  1. Hello. My name is Michael Tessin, and my father was Maurice Tessin. Emil Tessin was my uncle on my father’s side. I have some more information about his general life story. There is sometimes confusion about his history because he and his father had the same name. Emil disliked the idea of being Emil A. Tessin, Jr., and always listed himself as Emil A. Tessin II in his adult years.
    He had an additional sister, Mary Emily, and a younger brother Tom. His wife passed away a few years before he did, and he never emotionally recovered from that, which the family believes contributed to his own death.
