"Ferdinand Blumentritt (10 September 1853, Prague – 20 September 1913, Litoměřice) was an Austrian teacher, secondary school principal in Leitmeritz, lecturer, and author of articles and books in the Philippines and its ethnography. He is well known in the Philippines for his close friendship with the writer and Propagandist José Rizal, and the numerous correspondence between the two provide a vital reference for Rizal historians and scholars, including his last letter from prison before the execution." - (en.wikipedia.org 11.03.2021)
