William Allen Hadley (1860–1941), was an American educator, academic administrator, and advocate for the blind.
He married Jessie Henderson, a schoolteacher from Fox Lake, Illinois; together they had two children.
[citation needed] Hadley taught at Marietta College in Ohio, and in public schools in Peoria, Illinois (before 1900).
[1] To address the absence of educational opportunities for blind people, he began teaching braille by mail and established a school offering accessible, tuition-free classes for blind and visually impaired people.
When you think of the other fellow only and not yourself, your own problem fades into insignificance; in unselfishness lies the real thrill of being alive.
