What happened 1785 AD

Upon graduating in September 1785, Bonaparte was commissioned a second lieutenant in La Fère artillery regiment.

The earliest experimenter thought to have (unknowingly) produced X-rays was actuary William Morgan. In 1785 he presented a paper to the Royal Society of London describing the effects of passing electrical currents through a partially evacuated glass tube, producing a glow created by X-rays. This work was further explored by Humphry Davy and his assistant Michael Faraday.

Mozart stepped away from keyboard writing around the end of 1785, and started his famous operatic partnership with the librettist Lorenzo Da Ponte. In 1786 the popular premiere of The Marriage of Figaro was celebrated in Vienna. Later in the year its reception in Prague was even warmer.
