The Corps of Ceylon Electrical and Mechanical Engineers (CEME) was born on 12 December 1949 with the enlistment of 2/Lt. R.A.J Ratnam CEME. The CEME first became operative as a small workshop, located in the Army Headquarters premises under the advisory capacity of Capt. Roy Davies REME. Activities were initially confined to minor repairs to mechanical transport vehicles, armaments, small arms and the production of a large quantity of training stores. Later an engineer officer, Maj N.V Matthysz was appointed officer commanding and was its first commanding officer in the rank of lieutenant colonel. The unit moved to Kew Road, Slave Island (where its present Regiment Centre is) on 1 September 1950. This was a command workshop of the REME, and the CEME was fortunate to get the building with some of the available machinery as most of such machinery was back loaded by the British before the hand over. The CEME strength when moving to the new premises was 1 British officer seconded form REME, 2 Ceylonese officers, 4-seconded NCOs from the REME, 14 other ranks and some civilian tradesmen.
