Robert E. Dilworth

December 28, 1931 – January 19, 2022

A Memorial Tribute was held July 16 at 4 p.m. in the Dickinson auditorium.  

It was a great tribute to the remarkable founder of the amazing Dickinson Theatre Organ Society. A brief service was presented with Carl Black and John Baratta on the consoles, the entire Dilworth family was present, Bob’s son John spoke of interesting experiences with his father, soloists Dale Martin, Tina Sheing presented beautiful songs with Jonathan Bowen on the piano and a previously inputted performance by Peter Richard Conte had the Kimball play one of Bob’s favorite pieces of music – Bach’s Chorale Come, sweet death arranged by Virgil Fox. A Celebration Concert was then presented by Nathan Avakian and Dave Wickerham.  Profound thanks to Carl Black and all others for making this possible, from all of us in the DTOS Family of Friends.  To say Bob will be missed is a profound understatement.   

To honor Bob’s decades of work on behalf of DTOS, the DTOS Board of Directors unanimously voted to name our concert presentations as:

“The Robert E. Dilworth Memorial Concert Series”

Ben Forsthoffer

Ben’s love of the theatre organ started at age 5 when he first heard the Wurlitzer at Radio City Music Hall. Since then he has been fortunate to mentor with many of the top concert theatre organists present today and has played for numerous theatre organ groups. His determination to be part of the performing arts is driven by his enjoyment of the theatre organ. 


Juan Cardona

Juan began piano and organ study at the age of seven and continued musical training throughout his college career graduating with a Fine Arts degree at the University of Connecticut. He has been the House Organist for the Thomaston and Bardavon Opera Houses for over twenty years and has performed with the Boston POPS and many other prominent music venues. His DTOS appearance will include accompanying the 1921 Buster Keaton film “The Haunted House”.

The Dickinson Theatre Organ Society enjoys a well-known reputation for presenting premier performances on an internationally acclaimed instrument. 2019 was our 50th Anniversary Year of bringing the finest theatre organists from the world over to concertize for the general public. You are cordially welcomed and we thank you for your support! 

Over the decades of our existence, DTOS has enhanced our Mighty Kimball Pipe Organ from the typical 1920’s movie theatre instrument into a complete “unit orchestra” capable of presenting the full palette of musical expression from Popular to Classical. It is presently the fifth largest theatre pipe organ in the world. Click here to learn more.

Magic Is The Sound

Console News

Did you know that the Dickinson Kimball has two consoles? We have the three manual console that came with the nineteen rank organ built in 1928 for Philadelphia’s Boyd Theatre and a refurbished vintage Kimball console you see presently that has been updated with state-of-the art electronic controls to play the full 66 rank configuration of the present day organ. While the Boyd console was re-built many years ago with at the time “state-of the-art” controls, it has had a recent complete refurbishment so we can present two-console two-organist concerts again. Click here to read about this project from our  dedicated volunteer organ crew. If you’re wondering why two consoles, while it was rare, in the 1920’s there were organs installed in theatres with such, not only for the “wow” factor of seeing two people play at the same time, but also for the musically extravagant performances that can result. Radio City Music Hall in New York City has such still in operation today with the largest Wurlitzer built for a theatre.
