William Morrant Baker (1839 – 1896) was an English General Surgeon.
Baker lectured on physiology in St Bartholomew’s Hospital Medical School, and edited the 6th to the 13th editions of Kirke’s Physiology
Baker introduced the practice of removing the tongue in two halves (usually performed by splitting the organ longitudinally and then removing each half with an écraseur). In 1860 he invented the ‘duplex burner’ reading lamp. A metal bar residing within the long axis of the flame, just above the burner, divided the flame which burned more efficiently and provided greater illuminating power.
In 1873, under the title Erythema Serpens, Baker published the first description of Rosenbach disease (erysipeloid) an occupational skin condition secondary to infection with Erysipelothrix rhusiopathiae

Baker’s cyst (1877)
Baker’s paper of 1877 includes eight case reports in detail with three illustrations osteoarthritis is the underlying condition in several of the cases, in others the condition would now be called tabetic arthropathy or Charcot joints. Jean-Martin Charcot (1825-1893) had described arthropathy in 1865 but the subject had not become widely known. In 1921 Sir D’Arcy Power (1855-1941) showed that many of these cysts are part of a tuberculous affection of the joint [BJS 1921]
…in cases of effusion into the knee-joint, and especially in those in which the primary disease is osteo-arthritis, the fluid secreted may make its way out of the joint, and form by distention of neighbouring parts a synovial cyst of large or small size…the synovial cyst may be expected to disappear after a longer or shorter period, without leaving traces of its existence, even on dissection of the limb.Baker 1877
The series of synovial cysts in connection with joints was enlarged, and the pathology was placed upon a more sound footing, by contributions to the Pathological Society of London in 1885
…abnormal synovial cysts may be formed in connection, not only with the knee, but in connection with the shoulder, the elbow, the wrist, the hip, and the ankle joints…the synovial fluid on reaching a certain amount of tension by accumulation within the joint finds its way out in the direction of least resistance, either by the channel by which some normal bursa communicates with the joint, or, by forming first a hernia of the synovial membrane. In both cases, should the tension continue or increase, the fluid at length escapes from the sac, and its boundaries are then formed only by the muscles and other tissues between and amongst which it accumulates.Baker 1885
Baker’s cannula – a flexible tracheal/tracheotomy cannula/tube
The tube was made of ordinary India rubber, and answered the purpose for which it was intended very fairly ; but it was evident that a better material would be preferable, and the cannulae have been since constructed of vulcanized red rubber, a material which is in a high degree elastic, tough, and durable, and remains almost unaltered after long soaking in pus or other like fluids. The tube is single, and it has been found hitherto so easy of introduction and withdrawal, or , in other words, one tube can be so easily replaced by anotherBaker 1877
Sir D’Arcy Power (1855-1941) in 1921 demonstrated that the described ‘Baker’s cysts’ were often part of a tuberculous affection of joints, which had not previously been recognized by Baker. [Full Text]
