Wilhelm Henzen (30 November 1850 — 11 September 1910)
- died in the night between September 11th and 12th, more details can be found in 'Franz Brümmer: Lexikon der deutschen Dichter des 19. Jahrhunderts, 3. Band'
Careful to check time period and that to be at least fairly sure that Johann Heinrich Wilhelm Henzen (1816-87) (epigraphist) might not be meant instead.
