He would eventually be recognized as the first person to build Cajun accordions after World War II in Louisiana.
[3] Eventually, other Cajun musicians would play Brown's accordions, including Jo-El Sonnier, Boozoo Chavis[4] and Marc Savoy.
[7] Before World War II, Cajun accordionists favored German accordions, especially those made by the "Monarch and "Sterling" companies.
Even though John J. Mrnustik,[8] an owner of a music store in Houston, Texas and an immigrant from Eastern Europe, began making accordions after World War II, his prominence in Louisiana was small.
[9] He not only was able to help meet the post-war demand for new Cajun accordions but also established a reputation as an accomplished repairman throughout southwestern Louisiana, keeping many old pre-war German-made "Monarchs" and "Sterlings" alive and playing in the hands of their owners.
