In the early 1960s, Dr. Norman J. Holter invented and developed an electrocardiographic heart monitor small enough to be worn or carried by a patient. He and Willard Glassock, an engineer, were issued a patent for the device. Dr. Eliot Corday, of Cedars of Lebanon Hospital, collaborated with Holter and Glassock to promote the technology to both industry and physicians. He introduced Dr. Holter to Bruce Del Mar, whose company, Del Mar Avionics, developed a commercially viable monitor which came to be known as the Holter Monitor Test. Dr. Holter's Research Foundation ultimately sold exclusive rights to Del Mar Engineering Laboratories. Del Mar, which had previously manufactured military weapons training devices, became the acknowledged leader in Holter monitoring technology for over 40 years.
The collection documents the development of the Holter Monitor, a portable device for continuously monitoring heart activity for an extended period, through engineering logbooks, drawings, operator manuals, correspondence, photographs, sales brochures and catalogs, biographical information about the engineering staff who worked on the monitor, patents and trademarks, and marketing and sales materials.
