Keith Scobie-Youngs, Co-Founder, The Cumbria Clock Company (Cumbria, England)

In 2017, the Great Clock of Westminster—better known as Big Ben—was fully dismantled and removed from the iconic Elizabeth Tower for the first time since its installation in 1859. This unprecedented conservation project, completed in 2022, presented a once-in-a-lifetime opportunity to examine, restore, and future-proof the world’s most famous public timepiece.

At the June 2025 lecture of the Horological Society of New York (HSNY), Keith Scobie-Youngs, co-founder of The Cumbria Clock Company, will share behind-the-scenes of the entire five-year restoration process, from the meticulous disassembly and transportation of the 5.5-ton movement to the intricate conservation techniques employed by his specialist team. Every stage of the project was guided by a deep respect for the clock’s original craftsmanship and a commitment to ensuring its reliable operation for another 160 years and beyond.

Join Scobie-Youngs, lead conservator on the project, as he shares the challenges, discoveries, and triumphs of restoring this remarkable Victorian masterpiece to its full glory.

*Doors open at 5:30 PM ET, lecture to begin at 6 PM ET. RSVP is required.

** The lecture video will be available to members immediately, and to the general public following a two-month delay.

Eddie Landzberg, Horologist (New York, New York)

Before creating his famed marine chronometers (1730–59) to determine longitude at sea, John Harrison focused on land-based timekeeping, striving to build pendulum clocks of the highest possible precision. In the years following the Scientific Revolution and on the cusp of the Industrial Revolution, pendulum clocks governed travel, work, and daily life. The United Kingdom’s variable climate posed a special challenge for clock precision: colder air contracted metal pendula while warmer air expanded them, shortening and lengthening the swing period, respectively. In 1726, Harrison invented the gridiron pendulum. By connecting alternating rods of metals such as brass and steel, each with different thermal expansion rates, Harrison’s gridiron compensated for temperature shifts and stabilized the pendulum’s length and period.

At the May 2025 lecture of the Horological Society of New York (HSNY), Eddie Landzberg will present his undergraduate research on John Harrison’s gridiron pendulum. In an independent study at Harvard University, Landzberg examined Harrison’s original manuscripts in London and constructed a brass and steel gridiron pendulum. In his lecture, Landzberg will discuss the scientific discoveries, climate conditions, and horological innovations that set the scene for Harrison’s work. He will further discuss how the gridiron pendulum functions, reflect on its early reception, and share insights from the reproduction process.

Richard Newman, Antiquarian Horologist (DeKalb, Illinois)

A watch was one of the most expensive consumer goods that one could buy in early America. They were a technical mystery that embodied the very height of craftsmanship, fashion, and artistry in the world, and conveyed one’s stature in society.

At the January 2025 lecture of the Horological Society of New York (HSNY), Antiquarian Horologist Richard Newman will introduce “Early American Pocket Watches,” HSNY’s latest exhibit that spans 125 years of American watchmaking. From the earliest known American-signed watch, made in about 1715, to watches made during the early Federal period after the War of Independence, Newman will take us on a journey through the beginnings of an era that laid the foundations for the American watch industry.

*Doors open at 5:30 PM ET, lecture to begin at 6 PM ET. RSVP is required.
