I found this video dedicated to Akzidenz. :)
Akzidenz Grotesk is a realist sans-serif typeface originally released by the H. Berthold AG type foundry in 1896. Contemporary versions of Akzidenz Grotesk descend from an early-1950s project, directed by Günter Gerhard Lange at Berthold, to enlarge the typeface family, adding a larger character set, but retaining all of the idiosyncrasies of the 1896 face. Some new weights, condensed and extended widths were released under the title Standard. While Günter Gerhard Lange sought to academically retain Akzidenz Grotesk's imperfections, Max Miedinger's 1957 Swiss typeface Helvetica, used it as a model but sought to refine the typeface making it more even and unified. Akzidenz Grotesk also influenced Adrian Frutiger's 1958 typeface Univers. Akzidenz Grotesk is the first sans serif typeface to be widely used.
Akzidenz is sometimes at first glance mistaken for the Helvetica or Univers typefaces. The similarities of Helvetica and Akzidenz are apparent, but the subtle differences include the uppercase and lowercase C, and the uppercase G J, R, and Q:
