The
clerk with his head in the stars
He became a civil servant in the British war office, but soon dreamt of a life in astronomy...
After marrying Winifred James in 1858, Lockyer settled in Wimbledon, London, where he installed a six-and-a-quarter-inch telescope in his garden.
In 1865 he began looking at sunspots with a spectroscope—an instrument that uses prisms to split light into its constituent frequencies.

Studying light this way was a new technique in the 1860s. As chemical elements burn, they emit light with a unique spectrum of colour, like a multicoloured barcode.

On 20 October 1868 Lockyer peered down his garden telescope through this seven-prism spectroscope, now on display at the Science Museum in London. His weary eye barely believed what he saw…

Lockyer observed a rogue yellow line in a spectrum of light from the sun, quickly realising it might be a new element. He then called his wife, Winifred, to confirm his observation.
Winifred Lockyer was an active member of the Victorian scientific world, translating popular science books from French to English. She accompanied her husband on an 1870 solar eclipse expedition to Sicily.
Lockyer named the element helium, after the Greek sun god Helios.
He shared the credit for the discovery with French astronomer Jules Janssen, who independently observed the new element on an expedition to India.
In 1869 Lockyer was elected a Fellow of the Royal Society.
As if that wasn't enough, he also founded the influential scientific journal Nature that year.

Some years later, he built this observatory adjoining his house in Westgate-on-Sea, Kent.
Here, he made observations that laid the foundations for his his book, The Sun's Place in Nature.
On his retirement to Sidmouth, Devon, Lockyer secured support for the construction of another facility—the Hill Observatory—in 1912, renamed the Norman Lockyer Observatory after death in 1920.

Lockyer was one of the first people to identify a link between the sun's activity and weather patterns on Earth.

He was also instrumental in campaigning for the founding of the Science Museum, London.
