History
Sigma Co. Ltd was established in Melbourne in 1912, by Ernest Leete and Thomas Church, with the endorsement of the South Suburban Chemists’ Association. The impetus for such a move was driven by the high costs of wholesale drugs and medicines at the time, and Leete and Church set about manufacturing their own products for sale exclusively by members of the association. Established as a company to be funded by member subscriptions, initial interest from pharmacists was lukewarm, however Leete and Church persisted with their manufacturing plans. By the end of the first year however, the venture had attracted over two hundred subscribers, who agreed to the formation of a company owned by shareholders.
