    Pierre-Louis Guinand (1748–1824) was a Swiss lens maker.[1][2][3][4][5][6][7][8][9][10][11][12] who in the late 1700s came up with a breakthrough for making better quality and larger glass, and in time went on to teach a young Fraunhofer at Joseph von Utzschneider's (1763-1840[13]) glassworks, and eventually started his own optical glass works.[14] Guinand would supply glass for the Paris Observatory telescopes and also Cauchoix.[14] He was a pioneer in the manufacture of optical glass for microscopes, telescopes, glasses and other optical instruments.

He was born in La Sagne in the state of Neuchâtel. As good quality flint glass was difficult to obtain at the time, Guinand put himself to the task of producing it. After painstaking searches and trials, he succeeded in producing flawless flint glass of large dimensions.
