Robert Enzmann

In 1964, Dr. Robert Enzmann proposed a manned interstellar spacecraft that would be fueled by a
three million ton ball of frozen deuterium that would be contained in a cylindrical section behind that ball with the crew quarters.

The Enzmann starship was detailed in the October, 1973 issue of Analog, with a cover by space artist Rick Sternbach.

Enzmann was a GoH at Boskone 1, held September 10-12,1965 at the Statler-Hilton, Boston.
