This autograph letter signed by Albert Einstein features detailed calculations relating to the gravitational deflection of light, and is arguably Einstein's most substantial statement on the subject of gravitational lensing.⠀
⠀
The letter is addressed to Rudi W. Mandl, a Czech immigrant who was working as a busboy and restaurant dishwasher when he contacted Einstein to urge him to take more seriously the theoretical possibilities of gravitational lensing– something which is today fundamental to scientific efforts to understand the earliest epochs of the universe.⠀
