FWIW - quote of an entry from The Music Lovers' Encyclopedia (Gramercy):

Bohlmann, Th. H. Fr., Osterwieck am Harz, Germany, June 23, 1865 - Memphis,
Tenn., Feb., 1926; pianist; pupil of Dr. Stade, Barth, Klindworth, Tiersch,
d'Albert, and Moszkowski; debut Berlin, 1890; toured Germany 1890,
pf.-prof.  Cincinnati Cons.; later head of his own school in Memphis.

Looking at some of the Boellmann CDs, he seems to have written organ works
which leads me to think Stokowski may have conducted or performed some of
his works.

 [I also found a Klaus Bohlmann - who is an engineer/mixer on a couple - pop
music CDs - but since they are 1999....:-)]
