Ohlmarks is an incredibly fascinating and immensely productive writer in general, having produced a large number of translations and works on very disparate subjects. His doctoral dissertation was a weird one about arctic shamanism which Mircea Eliade was rather unimpressed by.
Fun fact, the Swedish translation of Lord of the Rings was considered so bad that the translator had a crashout over all the criticism and wrote a book accusing Tolkien of being a Nazi sorcerer.
