The original Paas Easter egg dye was invented in1893 by William Townley.
a drug store owner in Newark, New Jersey. He concocted recipes for home
products and figured out how to concentrate dye in tablet form and made
the modern Easter egg dyeing kit. The original price of each tablet was
five cents and customers would make the dye by combining the tablets
with water and vinegar. Townley eventually renamed his business the
Paas Dye Company. The name Paas comes from “Pasen,” the word
used by the Dutch for Easter. Paas is the largest manufacturer of
Easter egg dyes.
