On the completion of this undertaking in 1890 he was made K.C.M.G., and in the same year the Royal Society recognized his scientific attainments by electing him one of its fellows. Twelve years later at the formal opening of the Assuan dam, for which he was consulting-engineer, he was created K.C.B. Sir Benjamin Baker, who also had a large share in the introduction of the system widely adopted in London of constructing intra-urban railways in deep tubular tunnels built up of cast iron segments, obtained an extremely large professional practice, ranging- over almost every branch of civil engineering, and was more or less directly concerned with most of the great engineering achievements of his day. He was also the author of many papers on engineering subjects. He died at Pangbourne, Berks.
