1875 The first written record of permanent hair removal was reported in the St. Louis Clinical Record by Dr. Charles E. Michel, a St. Louis Ophthalmologist. Dr. Michel permanently removed ingrown eyelashes by inserting a needle charged with negative galvanic current into the offending follicles. The removal of the hair became known as "electrolysis".

1923 Dr. Henri Bordier of Lyon France developed the method of thermolysis.

1945-1948 Arthur Hinkel and Henri St. Pierre applied for a patent of the "blend" epilator and received it.
