Dr. Joseph Clover (1825-1882), an English physician, first described his Portable Regulating Ether Inhaler on Jan. 20, 1877. Clover was an especially sought after anesthesiologist and early pioneer in the specialty. This was the best-known of many inhalers that Clover designed. The dome-shaped reservoir was turned to points on a control dial to gradually increase or decrease the percentage of the air that passed over the ether. Several inventors based new inhalers on this, while the original continued to be manufactured as late as the beginning of WWII.

Clover was an especially sought after anesthesiologist and early pioneer in the specialty. This was the best-known of many inhalers that Clover designed. The dome-shaped reservoir was turned to points on a control dial to gradually increase or decrease the percentage of the air that passed over the ether. Several inventors based new inhalers on this, while the original continued to be manufactured as late as the beginning of WWII. Clover, to spare the patient the unpleasantness of induction with his "closed" inhaler (1877), suggested the "mitigated-ether" technique. The inhaler was fitted with a bypass tap for the reception of N2O. The bag was filled with the gas and anaesthesia was inducted a combination of N2O and asphyxiation. Ether was then admitted gradually by rotation of the bowl of the inhaler. When the patient had been duly "weaned over" to ether, the mask was lifted, the N2O allowed to escape, the bag refilled with exhaled air, and normal anaesthesia "a la Clover's inhaler" was continued.Metal domed chamber with a bulb attachment for rebreather bag, including a tap mechanism.

The Bruck Inhaler is a modification of the Clover Inhaler, designed by Lambert Bruck. Bruck added a glass dome which enabled the level of ether to be monitored during administration. This was a revolutionary change as it removed guess work from the process.The Bruck Inhaler is a historically, aesthetically and scientifically significant piece. The basic design is based on the Clover Inhaler, but with a rounded bottom. The idea of a glass viewing window was possibly inspired by Wilson-Smith Inhaler. The Bruck Inhaler is historically significant as it is the first inhaler to be made with a completely clear lower glass section. This improved the usability for the ether administrator, and eliminated much of the guesswork associated with dosage and ether levels, which in turn improved the patient experience. This piece provides a strong local link to both anaesthetic and general medical practice at the turn of the century. The design is credited to Ludwig Bruck of Sydney, and was presumably manufactured in the same area. Bruck, as the attributed designer, holds much relevance to the significance of the object, as connected with him is much historical information about the social context of medical practice. Ludwig Bruck was a prominent figure in the medical industry. He started his medical career in Sydney as a Medical Transfer Agent, and later owned a shop at 16 Castlereagh Street, Sydney. This business is listed in the 1903 Register of Firms as a Medical Agent and Importer of Medical Instruments and Books. Bruck was vocal as a journalist and published analyses of medical statistics, as well as the well known Australasian Medical Dictionary and Handbook, which included the “List of Unregistered Medical Practitioners”. Ludwig Bruck was an immigrant. He was of German descent, which placed him in a precarious position within Sydney society during the turn of century. Bruck conducted several public conversations with prominent members of the Australian Natives Association through the Sunday News in regards to his disagreement of the employment of medical practitioners by the ANA specifically to corroborate their health insurance policies. He was also a stalwart supporter of the Australian arm of the British Medical Association, being the publisher of the first and subsequent editions of The Australian Medical Gazette. Bruck chose to end his life with a combination of poison and chloroform on 14 August 1915, after being accused of trading with the enemy during World War One. His suicide note stated his horror at leaving his business partner to deal with the tarring of his reputation as the reason for his decision. The Bruck Inhaler has aesthetic significance as it is a beautiful example of turn of the century surgical design and craftsmanship. Aseptic methods of surgery were well known by 1909, and the aesthetic design of the Bruck Inhaler conformed to these principles. The ability for the surgeon to unscrew, clean and sterilize each part of the Inhaler contributes to the streamlined design of the piece. The Buck Inhaler holds scientific significance. There is the capacity for further research to be undertaken on the object. Geoffrey Kaye often collected multiple examples of equipment, usually one for reverse engineering and another for teaching. There are currently two examples of the Bruck Inhaler in the collection, presenting an opportunity for further technical research on the object. The inhaler is oval shaped with one half made of glass to allow observation of the ether level. A vertical cross tube, 22mm in diameter passes between the face-piece and the bag [missing]. There is a stopcock for admission of oxygen or nitrous oxide opposite the bag attachment. There is a central tube, 28mm in diameter, with controllable ports on either side. There is also a tear-drop shaped fask mask.Hand engraved on side of base: L. Bruck / Sydneyclover, joseph, bruck, lambert, inhaler, rebreather, nitrous oxide, oxygen, williams, probyn

In 1896 Robert James Probyn-Williams was appointed first honorary anaesthetist to the London Hospital and joined a select band of fulltime anaesthetists (26) in Great Britain. The Probyn Williams inhaler was a further modification of the Clover inhaler with narrow airways and rebreathing. The metal inhaler is ovoid shaped. The rotating gauge has a series of numbers engraved onto the inhaler for measurement. There is an elbow joint leading to a connector for attaching a re-breather bag, and at the other end is tap-style mechanism. There is a small glass bulb encased in a metal housing.

Sir Frederic W. Hewitt (1857-1916), an accomplished and well respected English anesthesiologist, was an expert in the function and use of the Clover Ether Inhaler. In 1901, Hewitt described his modification of the Clover Inhaler. Often referred to as the Hewitt Wide-Bore Inhaler, Dr. Hewitt introduced changes in order to make it easier to breathe through the device and improve the ventilation of oxygen and carbon dioxide. In 1901, Hewitt was recruited to anesthetize King Edward VII for emergency abdominal surgery. This was just a day or so before the new King was to be coronated. He recovered well, and Hewitt became the first anesthesiologist ever to be knighted. (Source: Wood Library Museum)Tall black round topped box with brass hooks at the sides and brass hinges at rear.

Dr Thomas Small designed this ether anaesthesia and analgesia machine while he was an Honorary Medical Officer at the Royal Women's Hospital in Sydney during the 1930s. The inhaler is compact and portable. Initially, Small experimented with other agents for the relief of labour pain but was not happy with any of them. He also tried various agents on himself, including nitrous oxide/oxygen, chloroform and ethyl chloride. Finally he settled on ether via a Clover inhaler as the best analgesic. This inhaler is only described in use in Australia and New Zealand, although it was used for almost 40 years. Black leather box with leather handle, lockable latches on either side and drop down front case panel containing a metal ether inhaler and length of black corrugated rubber hose with one end attached to the inhaler and the other end open for attaching a mask. The metal inhaler drum is circular and attached to the floor of the case with a small tap/lever to one side and a mixing valve on the top near the hose connection. The lever has incised gradings of quarter increments from 0 to 1.

Sir Frederick William Hewitt (1857-1916) wrote one of the earliest comprehensive textbooks on anaesthesia, and designed several pieces of anaesthetic equipment. In 1901, he described his wide-bore ether inhaler, a modification of the Clover Ether Inhaler. Unlike the Clover, it can be refilled with ether while still in use, and the mask is screwed into place so that it "cannot be unexpectedly detached." This version is a modified Hewitt's Inhaler which has a narrower 'ways' than the original Hewitt's, and no water compartment. Additionally, one side of the bowl is made of glass which enabled the person administering anaesthesia to see the level remaining in the bowl. Bowl shaped inhaler with a glass bowl base and metal dome top with a connector which appears to be for a rebreather bag. There is a metal switch at the base of the glass bowl to alter or regulate the flow.Stamped into central tube: COXETER LONDON Stamped into side of metal dome: 6460hewitt, wide-bore, clover, ether, anaesthesia, anesthesiology, anaesthesiology

Hurley, Sir Thomas Ernest Victor (1888-1958) was gifted this Probyn Williams inhaler in 1914. After studying at Melbourne University, Victorian-born Hurley was a Medical Officer at the Royal Melbourne Hospital until he commenced private practice in Collins Street. He was appointed Captain Australian Army Medical Corps, AIF and served in Gallipoli with the 2nd Field Ambulance. He served in Enypt, London, and the Western Front during World War 1. He gained a Companion of the Order of St George and St Michael in 1917. Upon return to Melbourne he held positions such as surgeon to Victoria Police (1928-1956), elected to Council of the Victorian branch of the British Medical Association, member of the Charities Board of Victoria and foundation member of the Royal Australasian College of Surgeons and chaired the Flying Personnel Research Committee m a consulting surgeon at the Royal Melbourne Hospital.
