The Rock Chalk Chant has been the battle cry of KU fans for over 100 years. This strange, traditional chant, which is among the most famous of all college cheers, was started by E.H.S. Bailey, a professor of chemistry.

Bailey wanted a cheer for his Science Club. Returning from a convention in Wichita, Bailey and some associates patterned the yell after the rhythmic cadence of their train rolling along the tracks. On May 21, 1886, Bailey submitted the cheer to his club. Originally, the chant was "Ray, Rah, Jay Hawk, K.U." repeating the words three times. This yell was used by the science club the next year and there were frequent allusions to "The Science Club Yell" in the student newspapers

An English professor suggested that "Rock Chalk" be substituted for "Rah, Rah" because it rhymed with Jayhawk and because it would be symbolic of the chalky limestone formations found on Mount Oread.

The chant was adopted as the college yell after the state oratorical contest in Topeka in 1886 because KU student yells for the their winners were enthusiatic, but unorganized. By the Fall of 1887 the yell was know as the offical yell of the school as the student newspaper reported on November 4, 1887,

"Every college of importance in this country has a college cry. In every town in which a college is situated, the midnight air resounds with the hideous yells of the student, symbolic of victory, defeat, or devilment. The students of the University of Kansas use their yell but little and it is only admidst great victory that "Rock-chalk-Jay-Hawk, K-U-U-U floats throught the midnight air reminding one of a band of Apache Indians."

By 1889 the form of the cheer had changed to the drawn-out cadence repeated twice, followed by three staccato repetitions.
