All were important players in the formation of Univ of MO. Shannon and Lampton ardent slave owners, Switzler a radical pro union man. As I dig through the info it appears Switzler worked hard to erase the history of many of the major slave holders of Boone Co.

As Kirby mentioned Lampton presided over the last public whipping of a slave in Boone Co. I believe this is the story:

COLUMBIA — It was 39 lashes for Tony, a slave who served as a janitor at MU.
One day in early 1861, he was brought to a meat market near the county courthouse, where a constable stripped him to the waist, bound his hands with rope and raised him up.
Each lash of the whip marked Tony's back with a blister or blood, a witness recalled decades later. The number of lashes came from chapter 25, verse three of the Book of Deuteronomy, which sets a limit of 40.
Tony had been charged with dousing a set of mules with acid, causing severe burns. The mules belonged to a man who had accused Tony of stealing a hog. The acid was traced back to the university's chemistry lab, and only Tony and a professor had the key.
In the 1850s and 1860s, the university used at least two slaves as janitors. Both were owned by relatives of MU President James Shannon, an ardent supporter of slavery.

As it turns out James Brown of Boone County has 28 slaves listed on the 1850 slave census. Boone County Obit Index relates him being Maj Jame Brown Sr. I haven't figured that one out but likely relates to 1812 service.

Switzler has been mentioned before as Col Cmdg 61st EMM with his own depredations with Krekel.
