Karl-Heinz Lange presented his first drafts of Rotola during a Typoart® type design competition in 1985 under the name “Boutique”. A year later, Norbert du Vinage, former manager of the type design department, integrated “Boutique” in his production plan. Due the Fall of the Wall, it took about 18 years until Lange finished this font family in cooperation with Elsner+Flake.

Karl-Heinz Lange was born on July 29, 1929 in Wiesenkirch in West Prussia. He was enrolled in the Humanistic Gymnasium at Elbing from 1939 to 1945 and changed to the Wernigerode High School after his family had to flee to central Germany. From 1949 to 1951, Karl-Heinz Lange studied at the Werkkunstschule Halle, where one of his teachers was Professor Post. After 1951, he continued his studies at the Hochschule for Grafik und Buchkunst in Leipzig with an emphasis on book design. He received his diploma in 1955 with distinction based on his design of a hot metal typeface.

From 1956 to 1961, Karl-Heinz Lange worked as a lecturer for Type and Commercial Graphics at the Hochschule für Angewandte Kunst in Magdeburg. From 1961 to 1963, he taught at the Hochschule für Grafik und Buchkunst in Leipzig, and finally as a freelance commercial designer in Magdeburg. He worked on a variety of assignments, one of which was the design of trick films. From 1969 to 1976 he took the position of Artistic Director of the Henschelverlag, Berlin; from 1976 to 1994 he was Professor of Type and Typography at the Fachschule für Werbung und Gestaltung in Berlin; and, until 2004, he taught at various institutes for advanced professional education. From 2005 to 2007 he taught at the Fachhochschule Magdeburg/Stendal.

Karl-Heinz Lange was awarded the second prize at the “International Type Design Contest 1971” for a headline typeface, and, in 1984, at the XI. Biannual of Graphic Design in Brno, he won a Silver Medal for the design of his typeface family Publica. He created the telephone book typeface Minima and re-designed the Typoart Super Grotesk® (Arno Drescher, 1930) as well as the Newspaper typeface Magna® by Herbert Thannhaeuser for the use on digital typesetting systems.

To the day of his death on June 29, 2010, Karl-Heinz Lange lived and worked as a type designer. Among others, he closely followed the designs of the typefaces which were developed under his guidance for Typoart®: "Publica®", "Typoart Super Grotesk®" and "Minima®" which he launched as “Publicala”, “Minimala” and “Superla” in 2009. In cooperation with Elsner+Flake, he developed the Typeface family “Rotola” between 2006 and 2009 as well as the script families of the "Viabella®" series. To the end, he followed the development of his first typeface, the “Diplom Antiqua”, which he also wanted to bring to market together with Elsner+Flake.
