Foster (1 September 1815 - 25 November 1904) was involved in the Latter Day Saint movement but was never a church member.
[2] The May 1, 1844, edition of the Nauvoo Neighbor contained a statement from Marshal Greene alleging that Foster "drew a double-barrel pistol on Mr. [Joseph] Smith".
[...] However, the three were arrested and brought before the Mayor [...] upon which evidence the court assessed a fine of one hundred dollars to each of the above-named aggressors.
During the Civil War, Foster served in key roles on the medical staff of the Union Army.
He served multiple terms as the city's mayor and was elected to the Mississippi State Legislature several times.
