Malcolm Goldstein

Malcolm A. Goldstein has possessed an abiding interest in stamps for as long as he can remember and aspired to be a serious philatelist until making a living and raising a family directly interfered. After renouncing stamp-collecting entirely and disposing of his holdings, he was inexorably drawn back to it when his nest was again empty, but tried to hone his interest to a narrow and manageable area of specialization. Battleship proprietaries seemed to fit that bill from a philatelic standpoint, but his cross-disciplinary approach of studying the patent medicine industry itself by mixing stamps, covers, the always more flamboyant tradecards and examples of the products themselves, never appealed to pure philatelists and has made him wary of philatelic societies. While an attorney by profession, he traces his interest in patent medicines back to the diathermy machine displayed in the office of his father, an old-fashioned “general practitioner,” which was in the basement of the family house. He was greatly relieved when assured some years ago, upon inquiry at the Museum of Questionable Medical Devices - then extant on its own and now apparently part of the Museum of Science in Minneapolis, MN - that the diathermy machine was a scientifically valid treatment utilizing heat to kill infections of the blood in the years before antibiotics

Robert Mustacich

Robert Mustacich is a member of the ARA, APS, the Institute for Analytical Philately, and the France and Colonies Philatelic Society. He is the president of the Collector's Club of Southern California for 2023-2024, and has won gold medal awards for his exhibits in revenue stamps, analytical philately, and postal history. Bob was lead author of the original Battleship Desk Reference that was published in 1999 with co-author Anthony Giacomelli. He led and organized the collaboration and creation of the present online BDR project.

Bob was trained as a physical chemist receiving his Ph.D. from Harvard University. He pursued a career in biochemistry, engineering, physics, and analytical chemistry instrumentation. He was an inventor and developer of commercial devices for low power, portable analytical chemistry instruments. He is the author of numerous publications, scientific and philatelic.

He was introduced to stamp collecting by his father who had a career with the U.S. Postal Service, working his way from a letter carrier to assistant postmaster. It was much later in some of his work involving pharmaceutical device physics that he learned about proprietary medicine tax stamps of the 19th century, and this rekindled his interest in stamp collecting in the 1980s. Always on the watch for fertile backwaters for research, he found the cancels on the 1898 proprietary stamps to offer a fascinating and vast area of opportunity for collecting.

In his spare time, Bob is a pianist and arranger of classical piano pieces for the piano. He also takes advantage of the Southern California climate and is a gardener of rare succulents. He is a past Vice President of the Santa Barbara Cactus and Succulent Society.

Paul Reese

Paul Reese, a life member of the APS since 1997 and a more recent member of the ARA, acquired his general philatelic interest as a child helping his parents with their world-wide collection. Paul has fond memories of sorting and identifying stamps by country and helping his parents mount stamps into their albums. Some specific memories include working through a group of British Colony issues from Australia and South Africa. As a young adult, he narrowed the scope of his collecting interests to US issues; regular, commemorative, and air-mail; focusing on unused singles. Paul continued this pursuit for 30-years.

Paul is now a retired Software Engineer and Manager. His career spanned different industries. His first role was in the telecommunications industry where he designed and built a platform to enable operator assisted long-distance telephone calls from hotels and payphones (yes, pre-cellphone ubiquity). As that industry began to constrict, Paul chose to make a change. His next role was in the financial industry, leading a team enabling credit-based products on the PayPal platform. After achieving multiple successes in that role, Paul changed industries again. His last change was to a government contracting company supporting systems that perform automated diagnostic testing of military components.

Approaching retirement, Paul shifted his philatelic focus, selling his US collection and changing narrowing his interest to the 1898 Proprietary Battleship issues with printed and hand stamped cancels. At the start of the Covid pandemic, Paul was approached by Bob to contribute to the BDR project.

Frank Sente

I spent most of my career working for the American Philatelic Society(APS) and the American Philatelic Research Library(APRL). While still a student at Penn State I started working part time at the APS helping manage the routing of stamp sales circuits and in the APRL. Although I had contemplated pursuing a law degree after graduating from Penn State, when offered fulltime employment at APS/APRL I chose that instead. While one who works for any non-profit doesn’t make scads of money, I never regretted my decision. It provided me the opportunity to work in a philatelic environment and allowed me the opportunity to meet and befriend a multitude of truly interesting people.

An early mentor impressed upon me that one has an obligation to give back to the communities in which they live and work, so I’ve belonged to various civic organizations and served a number of local non-profit boards both in State College, PA where I lived for 30 years, and in Prescott, AZ where I’ve lived for the last 20 years. Philatelically, I’ve served as an officer in the Mt. Nittany Philatelic Society and the Prescott Stamp Club and spent 8 years as the Exhibit Chairman/Jury Coordinator for ARIPEX. I’ve cut back, and now only serve on the board of the American Revenue Association.

I’ve always been more interested in the use of stamps and cancels then stamps themselves. In addition to the cancels used on the 1898 US battleship revenues, I have also collected Iceland numeral cancels, Spanish numeral cancels, and the squared circle cancels of Canada. My exhibit, Spanish American War Fiscal History:The US Documentary Taxes of 1898-1902, has won several ARA grand awards, and two WSP grand awards: MN STAMP EXPO 2014 and PIPEX 2019.
