The Observatory’s involvement with Chronometers dates back to 26 April 1766 when the Board of Longitude resolved that Harrison’s longitude watch (H4) along with his three earlier seagoing clocks should be tested there. Over the next 35 years, a small number of other chronometers were also tested for the Board.
A dramatic change took place in 1821 when the Astronomer Royal, John Pond, was made Superintendent of Chronometers for the use of His Majesty’s Navy. From that time onwards, chronometers took up vastly more of the Observatory’s time, with a dedicated Chronometer Department eventually being set up in the 1940s. In 1965, responsibility for the Department was transferred from the Astronomer Royal to the direct control of the Hydrographic Department of the Ministry of Defence as part of the transfer arrangements of the rest of the Observatory from the Admiralty to the Science Research Council.
One outcome of the 1818 Longitude Act was the creation of the post of Superintendent of Chronometers with an annual allowance of £100 a year. The first Superintendent was Thomas Hurd. He had nothing to do with the Observatory and was appointed in 1819. On 23 July 1821 (RGO5/229), the post was assigned to the Astronomer Royal, John Pond, who was paid the £100 allowance in addition to his existing salary. From that time onwards, the post was always held by the Astronomer Royal.
Following Pond’s retirement in 1835, the post was held by his successor George Airy, but with the separate allowance being incorporated into his salary as Astronomer Royal and the title falling out of general use, though it still appeared in the Navy List which was published annually. In 1881, the Superintendent post passed to William Christie. Soon afterwards, all references to it seem to disappear – perhaps because the post was formally abolished, or perhaps more likely, because the use of the title simply faded away as it had become synonymous with the post of Astronomer Royal.
Post holders from the Observatory:
1821–1835 John Pond
1835–1881 George Airy
1881– ? William Christie
According to a document written in 1835 by Pond for Airy (RGO6/72/223&226), one of the duties of the First Assistant Thomas Taylor was ‘to correspond with the Captains of ships respecting chronometers’. In the same document Pond wrote of Fredrick Simms: ‘ … in consequence of his having committed a great irregularity regarding the rates of chronometers, it is expected he will retire’.

From 1909 until 1941, the names of the staff employed and the departments or branches that they were allocated to were printed in the Annual Reports of the Astronomer Royal to the Board of Visitors. Although staff names and grades continued to be published in the reports after 1941, departmental information was omitted until 1958 when it once again began to be included. In general, the Reports from 1909–64 list by name those staff categorised as ‘non-industrial’ together with the names of just a handful of the many ‘industrial staff’.
From 1909 until 1914, chronometers were lumped together in a branch with time signals and the 28-inch refractor. This strange grouping came about in 1895. At that time, there were more areas of work than members of staff at the Assistant grades. Thomas Lewis, the officer who had been responsible for all aspects of timekeeping since 1882, was probably assigned this additional responsibility for the 28-inch refractor as he had developed a particular interest in the observation of double stars which he had been able to pursue alongside his main area of work.
No departmental information was published in 1915, 1916, 1917 and 1918 during World War 1. Following the retirement of Lewis in 1917, responsibility for the 28-inch refractor was uncoupled from time signals and chronometers. From 1919 until 1936, Time Signal and Chronometers were grouped together in a single Branch. With the retirement of its Head, William Bowyer in 1936, The Time Signals and Chronometer Branch became known as the Time Department and was headed by an outside appointee Humphry Smith. Its staff were specifically listed in the Annual Reports until 1941. At the outbreak of war, and the evacuation of some departments, the Time Department was effectively split into two. George Rickett was appointed officer in charge (but not Head) of the Chronometer Section. This was evacuated first to Bristol and then to Bradford on Avon. Humphry Smith was later evacuated with most of the rest of the Department to Abinger. By 1948 prior to its transfer to Herstmonceux, the Chronometer Section had become a Department in its own right. It was headed by George Rickett. Until 1958, his deputy was Arthur Shortland. Post 1958 it was AE Cordwell.
In 1964, all the ‘non-industrial staff’ were redeployed to posts in other departments in preparation for the transfer of the Department from the control of the Astronomer Royal to the direct control of the Hydrographer in 1965.
The names below have been extracted from these lists. The workshop came into being in 1937. As its staff were all of the industrial grade, their names are generally absent from the lists below.
