Fireside Chat ‘Alva Mason, Philadelphia Instrument Maker, 1824-1860’

January 14, 2023 @ 5:00 pm - 6:00 pm GMT

A brass plaque signed “A. MASON PHILADELPHIA”.

Presented by Steve Beare, USA.

The first instrument that inspired the author to collect and study scientific instruments, an inclined plane, was purchased in 1984. It has a brass plaque signed “A. MASON PHILADELPHIA”. No other examples of signed Mason instruments were located at the time.  In 1991 the author discovered and purchased a second signed Mason instrument, a double cylinder air pump. A third example was discovered in 2011 while watching an historical cooking TV series, A Taste of History. This led to Dickinson College in Carlisle, Pennsylvania, where it was discovered that they have an Atwood machine by Mason in the archives. This talk will give a short history of Alva Mason and describe the three known surviving Mason instruments.
Steve Beare collects 19th century scientific instruments and books on science and technology as well as 19th century American book bindings signed by the binder. He is a retired Research Chemist and lives in Wilmington, Delaware.
