Talk: Clocking Longitude, Master clockmaker John Harrison

Meet out front at ten to 1pm (12:50) and go in together
Join Lester Hillman for a talk about John Harrison, master clockmaker.

I have long been fascinated by historic issues with measuring longitude. Rather important for ships to know where they had sailed to! This problem couldn't be solved until clocks were accurate enough, and capable of functioning aboard ships.

Please join me. RSVP as soon as you know, I still need to request more tickets. The attendance fee is £2.50, thank you.
