Meet the Inventor

My motivation for creating this web site was to pay tribute to the inventor of the Select-o-matic mechanism, Edward F. Andrews.  While the completed product was certainly the achievement of not only Mr. Andrews but also the talented staff of Seeburg engineers, led by chief engineer Mahlon W. Kenney, it was Andrews' vertical play automatic phonograph that served as the start of it all …

Meet Mr. Edward F. Andrews

  I was able to secure information about Mr. Andrews from the fine people at The Chicago Community Trust and Affiliates.


The Select-o-matic is cited on page 2 of this pdf file.

 Accompanying the pdf file was the following summary from The Chicago Community Trust:


"Thank you for your inquiry. The E. F. Andrews Fund was established at The Chicago Community Trust in 1976 with a gift of $581,469.19 after Mr. Andrews’ family decided to terminate the family foundation, The E. F. Andrews Foundation.


Thanks to Mr. Andrews' kindness, over $4 million has been granted to Chicago-area non-profit organizations since his fund was established at the Trust."
