And just FYI, William Baird was a member of Beta Theta Pi, and recieved the inspiration to write his Manual during his college days. Baird was a member of Alpha Sigma Chi, which was absorbed into Beta Theta Pi in 1879. Baird was instramental in several other absortions by Beta Theta Pi, including the Mystical Seven Society in 1889.
