2023 Ward Francillon Time Symposium

Enjoy an introduction to David Rittenhouse and his world famous astronomical/musical clock at Drexel University.  Bruce includes a pictorial essay of the 2005 conservation and parts that make up the clock movement, including some interesting mechanical features.  Bruce will also highlight clockmakers and the evolution of clockmaking in Montgomery County, Pennsylvania.

Bruce R. Forman began his lifetime interest in horology when he worked for John B. Spencer, Sr., a clockmaker who serviced many of the historic clocks in the Philadelphia region.  Mr. Forman later authored some 40 articles related to the history of clockmaking and horological tools.  In the year 2000, he finished 13 years of research and published the book “Clockmakers of Montgomery County 1740-1850.”

He has served as President of NAWCC Philadelphia Chapter 1 and NAWCC Chicagoland Chapter 3 and is currently the editor of the “Tool Enthusiasts’ Round-Up” a newsletter devoted to the history and use of horological tools.  One of his most memorable achievements was to participate in the conservation of the world-famous David Rittenhouse astronomical/musical clock at Drexel University.
