History of Thiovanic Acid:
Scientist David R. Goddard, in the early 1930s, identified Thiovanic acid as a useful reagent for reducing the disulfide bonds in proteins, including keratin (hair protein), while studying why protease enzymes could not easily digest hair, nails, feathers, and such. He realized that while the disulfide bonds, which stabilize proteins by cross-linking, were broken, the structures containing these proteins could be reshaped easily, and that they would retain this shape after the disulfide bonds were allowed to re-form.
Thiovanic acid was developed in the 1940s for use as a chemical depilatory.
