We're thrilled to announce 'Eureka!', an online sale that journeys through the scientific and technological breakthroughs that have formed the modern world — and the brilliant minds that lay behind them.⠀
.⠀
Included in the sale are these Thomas Edison drawings for the light bulb, a WWII Enigma Machine, and the Nobel Prize medal awarded for the invention of IVF.⠀
.⠀
Thomas Edison built the first high-resistance, incandescent electric lamp in his Menlo Park, New Jersey laboratory in 1879 – the first successful test took place in October and the New York Times trumpeted the invention of the 'Edison Light' in their 21 December edition – but the carbonised paper filaments burned out within a few hours.⠀
.⠀
Undaunted, the inventor applied for the first patent on 4 November 1879 and over the next year a further 32 applications were sent from Menlo Park as Edison and his team tested thousands of filament materials: the discovery of a carbonised bamboo filament that could last over 1,200 hours allowed for the development of the forerunner of the modern lightbulb.⠀
⠀
The present drawings — available for bidding through 16 July — testify to Edison's continued work on the electric lamp throughout the 1880s, as well as offering an example of the related inventions that filled his design notebooks.⠀
.⠀
In March 1886, while on honeymoon in Florida with his second wife, Edison is considering adding additional electrodes to electric lamp circuits, which bears some similarity to the reed relays invented years later and used in telephone switches.⠀
.⠀
'Edison works on his lightbulb', Thomas Edison (1847-1931), 1880-1886. Estimate: £60,000-90,000.⠀

Eureka! Scientific breakthroughs of the 20th century — 24 June - 16 July, online.⠀
