History of anaesthesia: Overview

Abstract
The acquisition of an early ether inhaler stimulated research into several inhalers classified as Bruck inhalers. Ludwig Hermann Bruck was a German migrant who arrived in Australia in 1873. He became a medical publisher, importer of medical instruments, and made unique contributions to early Australian medical publishing, most significantly as the first publisher of The Australasian Medical Gazette. He also published The Australian Medical Directory and Handbook which contained lists of unregistered medical practitioners and alternative therapists. In 1914, Bruck joined in business with Richard Thomson who had a company selling medical equipment to doctors and hospitals. During the First World War, both Bruck and Thomson were charged with trading with the enemy. Bruck committed suicide in August 1915 before the case was heard in court. We did not find any evidence that Bruck designed the inhaler later attributed to him. The Bruck inhaler is functionally similar to the Probyn-Williams inhaler and should therefore be regarded as a glass-domed version of this inhaler.

Abstract
James Young Simpson's Notice of a New Anaesthetic Agent is a rare pamphlet of which three copies have hitherto been documented. Two of the three known copies were inscribed by Simpson with the words 'proof copy'. A fourth copy of the pamphlet, also inscribed with the words 'proof copy', has been identified. Although regarded by Simpson as a proof copy, there is previously unreported evidence that the pamphlet was advertised by the publisher on 12 November 1847, published on 13 November 1847, and sold on that day by booksellers in Edinburgh. Thus, the Notice pamphlet was the first published report of the use of chloroform as an anaesthetic agent. The pamphlet was issued 2 or 3 days before the well-known revised edition bearing the title Account of a New Anaesthetic Agent, and one week before the publication of Simpson's papers on chloroform in The Lancet and the Medical Times.
