The bible was divided up into chapters by Stephen Langton (archbishop of Canterbury in the early 13th century). The division of the OT into verses was done by a Jewish Rabbi, Isaac Nathan ben Kalonymus during the 16th century whilst Robert Stephanus, a Frenchman, completed the NT whilst travelling back and forward from Paris to Lyon on horseback. The fact that Beza used Stephanus' divisions in the Textus Receptus enshrined his divisions as the standard work.
Chapter and verse divisions are very handy but create artificial breaks in passages that were never intended. I have often thought how helpful it would be not to have them as then we would have to become muchmore familier with the bible in order to find things. here were no such divisions, you would need to memorise scripture more so you would know where to find things.
