Arthur Eichengrün (13 August 1867 – 23 December 1949) was a German Jewish chemist, materials scientist, and inventor.
 He is known for developing the highly successful anti-gonorrhea drug Protargol, the standard treatment for 50 years until the adoption of antibiotics, and for his pioneering contributions in plastics: co-developing (with Theodore Becker) the first soluble cellulose acetate materials in 1903, called "Cellit", and creating processes for the manufacture of these materials which were influential in the development of injection moulding.
 During World War I his relatively non-inflammable synthetic cellulose acetate lacquers, marketed under the name "Cellon", were important in the aircraft industry.
 He also contributed to photochemistry by inventing the first process for the production and development of cellulose acetate film, which he patented with Becker.

"; the third act is based on Jules Feiffer's "Passionella".
