Susman Brothers was a business partnership that united brothers Elie Susman and Harry Susman after they crossed the Zambezi river in 1901. The brothers were Jewish businessmen from Rietavas, western part of Russian Empire, now Lithuania. They founded, owned, and operated several large businesses in Africa. Elie Susman, the younger of the two, was the founder of Susman Brothers. However, it was not until 1907 that the business name of "E. Susman" was changed to "Susman Brothers".
Retail stores in Northern Rhodesia (now Zambia) date to the Susman brothers. Their business empire lasted over a century by overcoming logistical difficulties, physically challenging obstacles, and political changes. They developed an extensive trading, transport and ranching network, which stretched from Botswana to the Democratic Republic of the Congo. Though they operated in many different places, their main focus was always the country now known as Zambia.
Harry Susman worked as a peddler for a few years in Cape Town, South Africa, before crossing the Zambezi (at Kazungula) with Elia to buy cattle from King Lewanika of Barotseland in 1901.
The development of the Northern Rhodesian copperbelt began to take off, with the reorganization of the Bwana Mkubwa mine near Ndola in 1922. But Susman brothers pre-date to between 1916 and 1918. The brothers owned two concessions which covered part of what eventually became the Nkana Mine. The brothers' names still appear on the original title deeds. The Susman brothers eventually sold the claims for the Nkana prospect to William Lee, but retained the trading rights on the concessions. The brothers eventually become part of one of the richest copper mines in the world.
The Susman brothers heavily engaged, throughout the 1920s, in cattle buying along the line of rail. The Susmans supplied ivory bangles which were essential as trade goods. Their Leopards Hill Ranch near Lusaka Boma was used as a holding ranch, for cattle bought along the line of rail. Business was good for the Susman brothers; they asked the Northern Rhodesian government to enlarge the ranch. After complex negotiation with the government in 1927, the ranch was enlarged by 14,000 acres (57 km2), in two blocks taken from the Soil people reserve. The ranch had 400 people living on it, including 150 labourers. Also in the 1920s, the Susman brothers had planted up to 200 acres of wheat, as well as maize, at the ranch.
