KLATT, Johannes Emil Otto. Filehne, Posen (now Wieleń, Poland) 31.10.1852 — Bonn 27.8.1903. German Indologist. Son of postmaster Friedrich Michael Klatt and Caroline Fiedler. After gymnasium in Bromberg (Bydgoszcz) from 1868 studies of Indology under Weber at Berlin (also classical philology and history). Ph.D. 1873 Halle (A. F. Pott). Worked from 1874 as Assistant, from 1880 Kustos and from 1882 Librarian in the Royal Library in Berlin. In 1870-76 also stenographer at Prussian Herrenhaus. In the 1870s also learned Arabic, Syriac, Samaritan and Turkish in order to cope better with the Oriental collections of the Library. In the beginning of 1892 a sudden brain disease hospitalized him until his early death, first in Berlin, but soon in Bonn in a private psychiatric hospital. Married 1887 Margarete Patzig (1861–1928), two son (the pedagogue Fritz Klatt, 1888–1945, and the painter Albert Klatt, 1892–1970).

From c. 1882 on Klatt was working on a great Jaina Onomasticon, meant to be more than 1000 pages, but the work was interrupted by the illness, from which he never recovered, and only a specimen of 55 pages was published. The manuscript remains and is now worked upon by P. Flügel’s team. Their studies have also shifted and cleared up the confused accounts of his life. Thus, e.g. his friend Leumann in 1894 calls him on 1894 the late.
