About the author
Ned Katryn is credited as the author of Raporto pri la oka kongreso de esperantistoj (Krakovo 1912), a work connected with the eighth Esperanto Congress held in Kraków in 1912. The book survives in public-domain and library catalogs, including Project Gutenberg and Open Library.
Beyond that publication record, reliable biographical details about Katryn are hard to confirm from the sources available here. No clear birth-and-death information, fuller life history, or verified portrait turned up in the materials I found, so this overview keeps to the small amount that can be stated with confidence.
