Ernest Skinner went through a succession of name plates, after his short-lived partnership with James Cole, his solo nameplate read E. M. Skinner (1904-1919). With the financial backing of Hudson Marks, the firm was incorporated as Skinner Organ Co., in 1919. This arrangement allowed growth with factories in Boston and Westfield, MA, by 1927. The Skinner firm acquired the Steere Organ Company (successor to J.W. Steere & Sons) of Springfield, MA, in 1921. Skinner Organ Co. merged with the Aeolian pipe organ division of Garwood, NJ, in 1932, the merged corporation was titled Aeolian-Skinner Organ Co. (1932-1971)

Ernest Skinner acquired the Emmons Howard firm of Springfield, MA, and the Methuen Organ Co. of Methuen, MA, 1929 privately, not as part of the corporation. They latter would become the location of Ernest M. Skinner & Son, which Skinner established after leaving the firm he had founded and which still bore his name.

In 1919, the Ernest M. Skinner & Company was reorganized with Arthur H. Marks (former General Manager and Vice-President of the Goodrich Rubber Company) as the President and Skinner as Vice-President of the newly organized Skinner Organ Company. This allowed Skinner to focus on the technical and artistic aspects of the dozens of projects in which the company was involved at any one time, while others would manage the commercial aspects of the company.
