John Wieting

John Manchester Wieting (February 8, 1817 – February 13, 1888) was an American lecturer and philanthropist. He spent his early years as a teacher and then as an engineer and grader. After moving to Syracuse, New York, he read medicine to become a physician. After purchasing anatomical models he began giving lectures across upstate New York, gradually expanding the reach and the size of his lectures. They were extravagant affairs, and Wieting became known as one of the era's most prominent anatomical lecturers.

He retired from lecturing at the age of 45 in 1862, and spent his remaining years traveling the world and engaging in philanthropic efforts, mainly aimed at the development of Syracuse. Wieting funded construction of the Wieting Opera House in the city, which was open until 1930 and became a place for Broadway plays to be tried out. He has been cited by several scholars as one of the most famous anatomical lecturers of his era.
