Inez WHIPPLE-major contributions

Back 1

5 digit mammals have the same volar pad configurations.
Origin of epidermal friction ridges on the volar surfaces.
Ridge patterns are affected by external forces and pressures by neighboring ridges.

Front 2

Harold CUMMINS-major contributions

Back 2

Found volar pads regress at the same time as friction ridges develop.

aka Mr. Dermis
Confirmed double rows of papillae pegs in the dermis.
Pegs break into smaller ones with age, but it does not affect the ridges.
Confirmed that incipient ridges are the same as mature ridges.

What was Edward FOSTER's contribution to the field of fingerprints?

Back 4

RCMP member who created the first central fingerprint database in Ottawa.

Front 5

What was Alfred HALE's contribution to the field of Ridgeology?

Back 5

Concluded that differential growth plays a major role in the establishment of the morphology of the volar skin.

Front 6

What was J.C.A MAYER's major discovery?

Back 6

He was the first to recognize thta although specific friction ridge arrangements are similar, they are never duplicated.

Front 7

Who said "No two people in the world can have, even in a small area, the same sets of details, similarly related to the individual units?"

Credited with naming the original five details as dot, ending ridge, enclosure, bifurcation and island-GALTON details.
