Sigma was founded by two Melbourne pharmacists in 1912, it has grown to become one of the key players in Australia’s pharmacy industry .Edwin Thomas Church (1864 – 1947) and Ernest Holloway Leete a prominent chemist and a member of the College of Pharmacy who had established his own pharmacy in 1897. The entrepreneurial Leete had been part of a move in 1904 among a group of commercially-minded chemists to put up proprietary preparations. 1913 - 1927 Initially, the fortunes of the Sigma enterprise relied on E. H. Leete ‘working from home’, and even as late as 1915 company address was in Claremont Avenue Malvern. Following the establishment of the business in 1912, the Sigma Company Limited was located at Flinders Lane, Melbourne. Sigma – Tromax, 1928 E.H. Leete after sixteen years, said he would not stand again as a director of the company because interests were also turning elsewhere. He was assisting another company as its agent in the motor trade. 1938 to1953 was characterised by steady growth for Sigma, accelerated by manufacturing opportunities during World War Two. Between 1975 and 1996 the company was transformed as it entered a period of both consolidation and rapid growth. The appointment, in 1996, of new Managing Director, George Savvides, marked a break from the past. Today Sigma is a leading full line wholesale and distribution business to pharmacy.

Sigma Co. Ltd. (now known as Sigma Healthcare) was founded in 1912 by Melbourne Pharmacists Edwin Church and Ernest Leete and has since grown to become one of Australia's leading pharmaceutical retailers. Initially driven by the high prices of wholesale drugs and medicines, Church and Leete established Sigma as a manufacturer of medicinal products which could be sold only to paying subscribers. In 1913, it was decided that Sigma would open its markets to non-member pharmacies and retailers, although WWI caused production to falter. Over the following decade, the company grew, resulting in a restructuring in 1927 and the acquisition of small chemist manufacturing firm, Tromax Co. Ltd., who were struggling financially. For centuries, camphor has been used a folk medicine, likely used as a decongestant as well as a treatment for sprains and inflammation. In the 1900s, camphor was used as an analeptic by injection and was also used to induce seizures in schizophrenic patients in an attempt to cure psychosis. Camphorated oil, as was once present in this bottle, was composed of 20% camphor in cottonseed oil. It was rubbed into the skin as a topical medicine to treat itching from minor skin irritation. In 1947, a competitor's 1 oz. bottle of Camphorated oil was sold at a maximum of 8 dimes.
