From the founding of the studio in 1880 to its closing down in 1949, portraits of important people had been carefully selected from the huge archive of negatives. Over the years this "Gallery of Celebrities" was divided into several categories, for example, actors and singers, writers, musicians, scholars, politicians, industrialists, judges, aristocrats, clergymen, and foreigners living in Bohemia. The discovered boxes, most of which were 18 x 24 cm in size, had been marked with a system of Roman and Arabic numerals and inscribed with the names of the sitters, whose negatives the boxes contained. The Roman numerals indicated grouping by occupation; the Arabic numerals indicated the number of boxes in the individual categories. The precise system of labeling the boxes clearly shows the size of the discovery and allows us to envisage the extent of the loss of the "Celebrities Gallery."
