The Old Cottonians Association was officially started on 13th May 1910 when 17 Old Cottonians assembled in the Freemason's Hall in Simla. However, it is interesting to note that the first gathering of OC's was in 1878 when 28 old Cottonians attended the First Founder's Day function ever to be celebrated. This was held on the 27th of July as 28th fell on a Sunday. These OC's sat at the High Table for the meal that followed the function.
The OCA has now expanded to a large body and the Old Boys of BCS are actively involved.
