The design for Caprice was patented by Arthur M. Barnhart of Chicago in January-February 1888; rights were assigned to Barnhart Bros. & Spindler of the same city [USPTO D18035]. The affidavit claims that he “invented and produced” the design. This legal language is interpreted to mean that he did not personally draw the letterforms.
Considering that C.E. Heyer was employed by BBS as a designer-cutter in 1879–1897¹ and patented 35 typefaces plus ornaments assigned to this TF, it is likely that Caprice was the work of an independent lettering artist.
It is interesting to note that the patent applications for both Caprice and Colgate# were submitted on January 11 and both begin with the letter “C.” This circumstantial evidence suggests that both faces were designed by someone whose surname also began with “C.”
