Possibly Wenzeslaus Matiegka (1773-1830)?
There's a little bit of information in the "what's New" section of Leisner's web site. I also found this through G.o.o.g.l.e
"A Czech native, Matiegka studied law in Prague before he moved to Vienna to make a living in music. Shortly after 1800 he was active in Viennese amateur music circles. The guitar being as popular as the piano at that time, Matiegka perfected himself on both instruments, but the guitar became his favorite. By 1809 he was publishing sonatas for solo guitar with the best printers in Vienna and was billed as a 'piano and guitar master' on these editions.
Matiegka settled in the Viennese suburb of Leopoldstadt, where he became the Kapellmeister (music director) at St Leopold's parish church. His works included 23 published pieces for solo guitar, as well as many chamber pieces with guitar. He also wrote sacred music, which has been found in manuscript. He arranged works by Beethoven and Mozart in versions with guitar, and Schubert in turn arranged Matiegka's Nocturne op.21 for flute, violin and guitar as a quartet by adding a cello part."
Some of his music appears to still be in print.
