Leopold Ullstein (6 September 1826 – 4 December 1899) was the founder and publisher of several successful German newspapers, including B.Z.

They made the Berliner Zeitung am Mittag the first German newspaper to be sold by street vendors instead of by subscription.

They published the Berliner Illustrierte Zeitung, a new type of paper with many illustrations, photographs and drawings, from 1894 with a circulation of two million.

In 1919 the Ullsteins began publishing on a large scale, producing many other magazines on the sciences, the arts and literature, broadcasting, automobiles, and aviation.

[3][4] Following the rise of Adolf Hitler and the Nazi Party in 1933, the Ullstein publishing empire was forcibly "Aryanized."
