William Steinway’s diary: “H. Kammerer makes typewritten Copy of complaint agt Grotrian” –  this is the first time Henrietta Kammerer is mentioned as performing secretarial functions to William Steinway. She is probably the first woman to ever be employed by Steinway & Sons, and will work for the company for the next 37 years, first as a stenographer, then as Charles Tretbar’s assistant at the Concert and Artists department, and finally as the person in charge of routing of all the concert pianos for Steinway artists touring the United States. In all the years of her work in that role, a piano will never miss it’s scheduled encounter with a pianist.
