Roger Long

Roger Long (1680 – 16 December 1770) was an English astronomer, and Master of Pembroke College, Cambridge between 1733 and 1770.

He was educated at Norwich School and later admitted to Pembroke College, Cambridge in 1696/7.

He was ordained in 1716, and became Rector of Orton Waterville.

[2] One of the great characters of eighteenth-century Cambridge, he built a "water-work" in his garden and paddled round it on a water-cycle.

He also constructed a "zodiack", now considered to be the first planetarium, a hollow sphere that could hold thirty people showing the movements of the planets and constellations which remained in the grounds of Pembroke until 1871.
