Who is known as the 'Father of the Yellow School Bus'?

Frank W. Cyr is known as the “Father of the Yellow School Bus.” An educator and rural-school specialist, Cyr helped organize the first major national school-transportation standards conference in the United States in 1939.

Representatives from 48 states, bus manufacturers, transportation officials, and paint companies met at Teachers College, Columbia University. They agreed on 44 standards covering features such as body dimensions, aisle space, and visibility. The group selected a vivid yellow-orange shade because it stood out in early-morning and late-afternoon light and contrasted clearly with black lettering.

The color became known as National School Bus Chrome and later National School Bus Glossy Yellow. Cyr did not invent every part of the bus, and the conference did not create a single federal law forcing every district to use the shade. His lasting contribution was helping establish a shared national standard.

The title is sometimes confused with the Thomas family or Henry Ford because manufacturers shaped bus history, but the nickname belongs specifically to Cyr.
