From Tolkien Gateway

The Tea Club, Barrovian Society, also known as the T.C.B.S., was an organization that met regularly at Barrow Stores at King Edward's School in Birmingham. The core members were considered to be the "big four" of Tolkien, Geoffrey Bache Smith, Christopher Wiseman, and Robert Gilson.[1]

The friends continued to stay in contact with each other's literary work until 1916. Sidney Barrowclough and the Payton brothers, Ralph and Wilfrid, were younger than Tolkien and continued it for some time after they left.

Almost all of them died in World War I. Of Tolkien's close personal friends, only Christopher Wiseman survived the war,[2] a fact which greatly affected him.[3]
