Notably, his work with the young Samuel Clemens led to a literary appearance years later: writing under the name of "Mark Twain", Clemens portrayed him in the book Life on the Mississippi.
His translations into Estonian include two novels by Philip Roth, The Border Trilogy by Cormac McCarthy, the chapter "Waiting for Glory" from the novel The Web and the Rock and the novella The Lost Boy by Thomas Wolfe, and Life on the Mississippi by Mark Twain.
