Gerald Lange is the proprietor and founder (1975) of The Bieler Press, a small printing and publishing firm that specialized in studio letterpress, typographic design, and the publication of finely-printed limited edition books and related matter. The Bieler Press has provided photopolymer platemaking to the contemporary studio letterpress community since 1995.

In 1991, Lange was selected as the first recipient of the prestigious Carl Hertzog Award for Excellence in Book Design (in 2014 he was asked to serve as a judge for the 14th Award). His publications have also won awards from the Type Directors Club, the American Institute of Graphic Arts, and the Chicago Book Clinic.

Lange has written extensively on typography and the book arts, contributing articles for publications such as Parenthesis (FPBA), book art object (CODEX), Printing History (APHA), Bookways, and The Typographer.

His seminal monograph, Printing Digital Type on the Hand-Operated Flatbed Cylinder Press, was first published in 1998. The 5th edition (Chatwin, 2018) is available now.
