Joannes Evangelista Purkinji found that the patterns on one’s finger tips and the ridges and lines on one’s prints begin to form at around the thirteenth week in the womb.

Dr. Jan Purkinje classified the papillary lines on the fingertips into nine types: arch, tented arch, ulnar loop, radial loop, peacock’s eye/compound, spiral whorl, elliptical whorl, circular whorl, and double loop/composite.
