This man is identical with Bernard Anton Guttmann (Bernard Anton Guttmann)
See also his grave on the New Jewish Cemetery in Tábor (the cemetery was destroyed in 1941):

I also found another photograph with a clearly identical man and the name "B. A. Guttmann":

(There is also other Guttmann on the plate: JUDr. B[edřich] Guttmann, another important member of the local Jewish community - and a member of the city council.)
