A study of the frequency of fingerprint patterns reveals an
eminent fact, that the second and seventh digits (index fingers) distinctively
display a greater variety of patterns.
This event is noteworthy when looking at the fingerprint record of
former president Dwight David Eisenhower.
All of the digits of Eisenhower's left hand displayed the ulnar loop
pattern with the exception of the index finger.
His left index fingerprint was a plain whorl pattern, a clear departure
from pattern consistency. However, this
phenomenon is not the most striking example of departure because two other
whorl patterns are displayed on the right hand.
They are located on the # 1 and the # 4 digits.
President Eisenhower's most
prominent departure from pattern consistency was with the right index (# 2)
fingerprint. It was a radial loop
pattern and the only radial loop displayed in the ten set of fingerprints. A study on the frequency of fingerprint
patterns including 17,951,192 males concluded that 18.64951920741531% of the
male population displayed the radial loop pattern on the right index. In addition, this was a radial loop with a
ridge count of 15 which makes it 1.043418175
% of the NCIC FPC for the right index. President
Eisenhower was a member of the 1% club in fingerprint classifications.
