Educated at St George’s Hospital, and became an Assistant Surgeon in the Grenadier Guards on April l3th, 1838. He served with his regiment for upwards of thirty years. His promotions were Battalion Surgeon Oct 1st, 1854, and Surgeon Major January 24th, 1858. He retired on half pay with the rank of Deputy Inspector-General of Hospitals on December 12th, 1868. He served as Surgeon of the Grenadier Guards through the Crimean Campaign from December, 1854, and was present at the siege and fall of Sebastopol, receiving the Gold Medal with Clasp, Turkish Medal, and Order of the Fifth Class of the Medjidie. His biographer in the *British Medical Journal* (1894, ii, 789) remarks : “Mr Blenkins has so long retired from active work that the younger generation will hardly recognize his name as one of the most active and valued workers in the metropolis some thirty years ago. He was one of that distinguished class of army surgeons, then by no means too numerous, who to a thorough knowledge of his profession and departmental duties, added a great love of scientific research in the active study of its most difficult departments. He was a practical and skilful histologist, when to be so was a rare distinction even in the schools in civil life. We incline to believe that he was the first amongst the teachers of histology in the metropolitan medical schools who instituted classes of practical microscopic work and demonstration. He lectured and taught at Lane’s School of Anatomy and Medicine adjoining St George’s Hospital, and as far back as 1851 he carried on there a class of practical histology in which every student was provided with a microscope, and was taught himself to make, prepare, and put up the specimens. This class Mr Blenkins conducted while a surgeon in the Guards, and it had, at that time at least, few if any parallels in this country, for what is now an everyday rule of teaching was then a rare and brilliant exception.” The same biographer refers to him as one of the most lovable and accomplished surgeons of his day, a man of handsome presence and great refinement and dignity of manner, singularly modest and markedly reserved. His native kindliness chiefly showed itself in the welfare of his former students. He died at Worthing on September 26th, 1894. His London residence was at 9 Warwick Square, SW.
