The period from 1900 until approximately 1950 in America has become known as the Golden Age of the Accordion. Marion Jacobson, in the 2007 article “Searching for Rockordion”, comments that “it was truly an era worthy not only of the name Golden Age of the Accordion, but Golden Age of Music making among middle-class American families”. During this time, the design of the stradella piano accordion reached maturity and the accordion rose to prominence as one of the foremost popular concert instruments of the day.
