Perkins Brailler
Overview
The Perkins Brailler is a specialized typewriter designed for writing in braille, a tactile writing system used by people who are blind or visually impaired. Developed at Perkins School for the Blind in Massachusetts, it significantly lowered the cost and complexity of producing Braille text, becoming the standard tool for Braille literacy for decades.

Historical Context & Development
- Predecessors: Early Braille writing relied on the slate and stylus (low-tech, slow) or expensive embossing machines.
- Invention: Developed in the 1950s by Robert Irwin (also known as Bob Irwin), a blind teacher at Perkins.
- Design Philosophy: Irwin aimed for an affordable, durable, and intuitive machine mimicking standard typewriter layout but with six keys corresponding to the six dots of the Braille cell.
- Launch: First produced in the 1960s; success driven by mechanical simplicity and low production cost, enabling global accessibility for schools and individuals.
- Cultural Impact: Featured in “Perkins Brailler: the World at Your Fingertips” by Our Own Devices, highlighting its role as pivotal adaptive technology.
Key Features
