Google honours British chemist Perkin with sketch doodle on his 180th birthday”

GOOGLE / GETTY SIR WILLIAM HENRY PERKIN: Google Doodle are celebrating the British chemist Who was Sir William Henry Perkin? Investigating the substance further, Perkin incorporated potassium dichromate and alcohol into the aniline at different stages and chanced upon a deep purple solution.

During the rest of his life Perkin manufactured other synthetic dyes including Britannia Violet and Perkin's Green, as well as discovering the first synthetic perfume chemical coumarine.

The Science Museum in London said: "If you were an average person in the 1850s your wardrobe would have been made up of many shades of beige and browns".

It was adopted by Queen Victoria and by by Empress Eugénie, wife of Napoleon III, in France.

Perkin could not have chosen a better time or place for his discovery: England was the cradle of the Industrial Revolution, largely driven by advances in the production of textiles; the science of chemistry had advanced to the point where it could have a major impact on industrial processes; and coal tar, the major source of his raw material, was an abundant by-product of the process for making coal gas and coke.

Perkin persuaded his father to put up the capital to support his enterprise and his brothers to partner with him to build a factory. He was unsuccessful in his attempt to synthesise quinine but in a related reaction a mysterious dark sludge was produced.

The chemist continued his research and his passion for dyes - having developed and introduced aniline red in 1859, aniline black in 1863 and alkylate magenta in 1864.

This was the flawless time for Perkin to have made his discovery and he went about getting his father to invest in his discovery, which caught on in Britain's booming textile industry right away.

All three sons, William Jr, Arthur and Frederick, became chemists. Today marks the 180th birthday of Sir Willian Henry Perkin and apart from mauveine, he is also known for aniline dye and Perkin triangle.

He was buried in the grounds of Christchurch in Harrow.
