This 1975 bust of John Flamsteed was made to observe the tercentenary of the Greenwich Observatory. It is made of Tisbury stone and the sculptor is G.E. Elliot.
Wikipedia (visit link) informs us that Flamsteed:

"...was an English astronomer and the first Astronomer Royal. He catalogued over 3000 stars.
Flamsteed accurately calculated the solar eclipses of 1666 and 1668. He was responsible for several of the earliest recorded sightings of the planet Uranus, which he mistook for a star and catalogued as '34 Tauri'. The first of these was in December 1690, which remains the earliest known sighting of Uranus by an astronomer.

On 16 August 1680 Flamsteed catalogued a star, 3 Cassiopeiae, that later astronomers were unable to corroborate. Three hundred years later, the American astronomical historian William Ashworth suggested that what Flamsteed may have seen was the most recent supernova in the galaxy's history, an event which would leave as its remnant the strongest radio source outside of the solar system, known in the third Cambridge (3C) catalogue as 3C 461 and commonly called Cassiopeia A by astronomers. Because the position of "3 Cassiopeiae" does not precisely match that of Cassiopeia A, and because the expansion wave associated with the explosion has been worked backward to the year 1667 and not 1680, some historians feel that all Flamsteed may have done was incorrectly note the position of a star already known.

As Astronomer Royal, Flamsteed spent some forty years observing and making meticulous records for his star catalogue, which would eventually triple the number of entries in Tycho Brahe's sky atlas. Unwilling to risk his reputation by releasing unverified data, he kept the incomplete records under seal at Greenwich. In 1712, Isaac Newton, then President of the Royal Society, and Edmund Halley obtained the data and published a pirated star catalogue. Flamsteed managed to gather three hundred of the four hundred printings and burned them. "If Sir I.N. would be sensible of it, I have done both him and Dr. Halley a great kindness," he wrote to his assistant Abraham Sharp."

As for the crater, Wikipedia (visit link) informs us:

"Flamsteed is a small lunar crater located on the Oceanus Procellarum. It lies almost due east of the dark-hued Grimaldi, and north-northwest of the flooded Letronne bay on the south edge of the mare.

The rim of this crater is not circular in form, having a bulging rim to the southeast. The interior is relatively flat and undistinguished by impacts. The crater lies within the southern rim of a crater that has been almost completely submerged by the basaltic lava flows that formed the Oceanus Procellarum. All that remains of this feature designated Flamsteed P are some low ridges and hills arranged in a circular formation.

The Surveyor 1 craft landed within the northeast rim of the buried Flamsteed P feature, about 50 kilometers north-northeast of the Flamsteed crater rim."
