Jacob Zeilin Becomes First Brigadier General Commandant in USMC History
On March 2, 1867, Jacob Zeilin, who had served as Colonel Commandant of the Marine Corps since June 30, 1864, was promoted to the rank of Brigadier General Commandant, the first time Congress authorized this rank for the Marine Corps. This statute was repealed in June 1874 so that the rank of Commandant would revert to colonel upon Zeilin's retirement.
