Glenn Fleishman is a writer, historian, and designer, with a focus on 19th and 20th century print production, and modern Apple products. Glenn began writing for periodicals when he was in grade school and never stopped. He contribute regularly over his career to publications that include the Economist, the New York Times, Fortune, Fast Company, Wired, and Macworld, and has been an editor or contributor to the long-running technology newsletter-turned-website TidBITS for nearly 30 years.

Having obtained a degree in art with a graphic design concentration from Yale in 1990, Glenn proceded to work in a number of unrelated fields. He spent nearly two years at the Kodak Center for Creative Imaging in Camden, Maine, and at an associated production company; worked as managing editor at a computer book packaging company; joined Amazon.com for six delirious months before he woke up and left; and then shifted into writing more or less full time, with a sideline of coding webcommerce and content management systems.

More recently, Glenn was the editor and publisher of The Magazine (originally founded by Marco Arment), a designer in residence at the letterpress program at the School of Visual Concepts, Seattle (now the nonprofit Partners in Print), the creator of The Tiny Type Museum & Time Capsule executed with woodcrafter and designer Anna Peterson, the author of London Kerning, Six Centuries of Type & Printing, and How Comics Are Made (Andrews McMeel Publishing, 2025).
