About MOS
Business card circa 1972
Maryland Organ Service began in 1972 as a "retirement plan" for James Henthorn. At that time, he, a lifelong church organist and physics graduate of Johns Hopkins University, having spent most of his career life as an engineer at Hopkins Applied Physics Laboratory and at the Bendix Corp., decided that "fixing 3 or 4 organs a month" would be a good way to occupy himself in his retirement.

He was wrong.

Not only did he fix many more organs than that "3 or 4 a month" but he also was delightfully surprised to find there was a great market for organ repair.

From 1969 or so, until 1972 Mr. Henthorn repaired organs on a "side job" basis. During this time he began to establish himself as a technician for many manufacturer's. By the mid 70's he had accomplished being "factory Authorized" by almost every major manufacturer and had achieved "Master Technician" status with the Hammond Organ Company.

During the 80's he achieved status as a member of the "Baldwin Master Organ Guild" and joined as a charter member of MITA (Musical Instruments Technicians Association) International.

On December 31st 1995, James E. Henthorn, Jr. retired from "active" service with MOS, although he still occasionally provides me with a helping hand as I did for him so many years ago.

It was during the summer of 1975 that I, at age 5, began my career. Crawling into the chambers of a pipe organ, I tuned my first pipe.

It took almost 30 minutes! Now I can tune an entire rank (61 pipes) and more in that time.

From there, spending summers tagging along on service calls became a tradition. It wasn't long before I started "toying" with electronics and reading technical manuals. I continued to do more mechanical work, holding keys, taking off and reinstalling organ backs, etc. By my high school years I had enrolled in a 3 year "Computers, Electronics and Robotics" course offered through the school system, and concurrently was instructed in "Vacuum Tube Technology" by my grandfather, Mr. Henthorn.

In 1988 I became a full fledged employee of Maryland Organ Service. Though I left in 1994 to work at a local pipe organ restoration shop. I returned in winter of 1995-96 to take the reigns of Maryland Organ Service.

In 2005, MOS was absorbed into Speakeasy Vintage Music.  MOS became a new service mark, focused on the same high quality restorations that Speakeasy was already known for in a new market; Institutional.  Our first Opus was the reconstruction of a 1960's Allen installed in St. Vincent DePaul church in Baltimore.

With the former controls ravaged by age and a rodent invasion, the system was disassembled and converted to digital control. This allowed the console a heretofore unknown degree of freedom, no longer being tethered by the large and cumbersome cable that had been used in the original installation.
