The collection provides documentation for 79 artifacts—including telephone answering machines, cellular phones, and related wireless devices—which Henderson donated to the museum's Electrical Collections holdings. Compiled by Henderson to accompany the artifacts, the materials document the history and development of cellular phones and related wireless devices. The materials are arranged into twelve series and reflect the original order in which Henderson created them. Henderson assembled books/binders of material with numeric dividers. There is no index nor is there a key to the four-letter alphabetical acronyms used in books four, eight and nine.

Biographical / Historical
Biographical / Historical
Dr. Kazuo Hashimoto, widely recognized as the father of the modern answering machine, was an inspired technologist who developed thousands of advancements in the field of telephony. Hashimoto registered over 1000 patents throughout the world, over 800 of which are related to the telephone answering device. In 1993, inventor Daniel Henderson became an apprentice of Hashimoto and worked with him on licensing, management issues, and infringement analysis. After Hashimoto's death in August 1995, Henderson turned his attention to ensuring that Hashimoto's work would be respected in the telecommunications and computer industries. In 1996, Henderson and Hashimoto's widow co-founded PhoneTel Communications, a company dedicated to protecting the patent portfolios of inventors including Hashimoto. By successfully licensing with nearly every telecommunications and computer company, Henderson made sure Hashimoto's work was respected and rewarded.
Henderson has broad experience in the creation, management, and licensing of intellectual property. He also holds numerous patents in telephony and communications. Henderson was formerly with IBM Corporation and received the "Distinguished Alumnus Award" from Southern Oregon University. Henderson worked with Jack Kilby, who received the Nobel Prize for Physics in 2000 for the invention of the world's first integrated circuit (IC) chip. At the time this collection was donated, Henderson presided over several companies including PhoneTel Patent Services, PhoneTel Communications, and Pinpoint Incorporated. Henderson's many ties to the New Jersey Institute of Technology (NJIT) include establishing the PhoneTel IE Inventions and Patents Fund, the PhoneTel Endowed Graduate Fellowship Fund, and involvement in creating a new course entitled "Inventions and Patents." He was the commencement speaker when NJIT first presented the Hashimoto Prize in 1998.
