b. 1873
A Canadian-born scholar of German literature, Braun is best known for a focused, early-20th-century study of Weltschmerz—the mood of world-weariness in poetry. His work turns big, melancholy ideas into clear literary analysis centered on Hölderlin, Lenau, and Heine.

by Wilhelm Alfred Braun
Born in 1873, Wilhelm Alfred Braun was a literary scholar whose best-known book is Types of Weltschmerz in German Poetry. The Library of Congress records the book as a 1905 publication from New York and notes that it was submitted as a Ph.D. thesis at Columbia University.
Project Gutenberg and the Library of Congress both identify the book as a study of German poetry and literary pessimism, with sections on Hölderlin, Lenau, and Heine. Braun presents Weltschmerz not simply as pessimism, but as a distinctive emotional and poetic response to suffering and disillusionment.
Reliable biographical detail about his personal life is limited in the sources I could confirm here, so this overview stays close to what is clear from the record: Braun wrote in English for an academic audience and produced a concise, influential piece of literary criticism that has remained available through major public-domain archives.
