The last few years before World War II were arguably the most fascinating and creative in modern blackletter design. During those years, and as demonstrated with the grid-based Leather font, the geometric sans serif was influencing the blackletter forms, taking them away from their previous Jugendstil (Art Nouveau) hybridizations. Blackhaus is a digitization and elaborate expansion of a typeface called Kursachsen Auszeichnung, designed in 1937 by Peterpaul Weiss for the Schriftguss foundry in Dresden. This is one of very few designs from that time attempting to infuse more Bauhaus than Jugendstil into the Blackletter forms. This is why we used a concatenation of the words blackletter and Bauhaus to name this face.
The result of injecting Bauhaus elements into blackletter turned out to be a typeface that is very legible and usable in modern settings, while at the same time harking back to the historical forms of early printing.
The original 1937 design was just one typeface of basic letters and numbers. After digitizing and expanding it, we developed a lighter version, then added a few alternates to both weights. The Rough style came as a mechanically-grunged afterthought, due to current user demand for such treatment.
Having the flexibility of 2 weights and many alternates of a blackletter typeface is not a very common find in digital fonts. More specifically, having the flexibility of 2 weights and alternates of a 20th century blackletter typeface is almost unheard of in digital fonts. So the Blackhaus family can be quite useful and versatile in an imaginative designer's hands.
