If you missed the first part…
The second half of Hasse’s career showed moments of production followed by large gaps. He wrote his only novel in 1968, The Stars Will Wait, a space opera. After this he retired again to appear one last time in Whispers, writing two horror tales for Stuart David Schiff. Writing Horror may seem odd for a man who liked space opera but Hasse did pen the Cthulhu Mythos tale “The Guardian of the Book” for Weird Tales in 1937. Like other old-timers, Frank Belknap Long, Carl Jacobi and Emil Petaja, Hasse allowed himself one last outing in the pages of the small press.

Conclusion
Henry Hasse’s career spanned four decades of Science Fiction. His work will be seen as that of a hobbyist perhaps, but he did manage to sell stories to ten famous editors including Hugo Gernsback, T. O’Conor Sloane, F. Orlin Tremaine, Farnsworth Wright, Fredrick Pohl, Malcolm Reiss, Ray A. Palmer, Howard Brown, Frederick Dannay and Cele Goldsmith. He never sold to John W. Campbell, but you can’t have everything. He got to chum around with the likes of Ray Bradbury, Emil Petaja and Hannes Bok, so there’s compensations for not being an Astounding Science-Fiction author. What fan could ask for more?
