    Back in April 1939 and armed with $5,000 provided by the Rockefeller Foundation, Columbia University Teachers College professor Frank Cyr took a tour of ten states to make a research about school transportation problems. What he found was that many students had no dependable way to get to school and the ones who did often traveled in unsafe buses in the over 100,000 school areas.

Seeing a need to fix this problem, Cyr organized a meeting- one that would change the future of school buses forever. School officials and transportation experts met to set much-needed standards for buses, including those for color, height and width as well as safety rules that hadn’t been set before or that were different in every state.

There were many different bus colors in the US before this meeting; several areas even planned to have red, white and blue buses as a way of encouraging students to love their country. Cyr presented his new choices to education officials, a reported “50 shades(色度) changing from lemon yellow to deep orange-red”. The matter was settled quickly. Yellow, or “National School Bus Glossy Yellow”, was chosen because it was quite striking, making the school bus easy to be seen. Besides, it made the bold(黑体的), black writing on the side of each bus clear. (The bold, black writing gives information about each school area, telling students which school bus they could take during early morning and late afternoon hours.) Thirty-five states made the changes quickly, and every state was on board by 1974.

Being recognized as the “father of the yellow school bus”, Frank Cyr has surely influenced your life if you ever rode a school bus or saw that noticeable color pulling up to your stop on a dusky morning.
