Portrait of Jan Štěpánek (1844-1916), a pharmacist in Královské Vinohrady, Bohemia (present-day part of Prague, Czech Republic). The picture is cropped from a gallery of pharmacists, who organized the 2nd international pharmaceutical expo in Prague in 1896. According to the caption, the photos in the gallery were taken by Jindřich Eckert (1833 - 1905), Jan Mulač (1845 - 1905), Jan Tomáš (1841 - 1912) and J. F. Langhans (1851 - 1928) without specifying who took each particular one. So, we cannot tell who the author is but we can confirm that it is in public domain.
