Born in Bowery, New York, U.S.A., 15.9.1871 and died in Johannesburg, 11.3.1949, Schlesinger was a financier and pioneer of the South African entertainment industry. He was the second son of the family of ten of Abraham Schlesinger, a Hungarian-Jewish immigrant. The European branch of the family owned a saw-mill in the Patra mountains on the border of the present Czechoslovakia. Since the mill could not provide a livelihood for the whole family, two brothers, Abraham and Moritz, emigrated to America and started their career by splitting wood, Abraham later going into the cigar business and then opening a bank.Schlesinger grew up on the outskirts of the Bowery, the East Side district of New York, helping, as a boy, to supplement the family income by peddling hair-clips and selling newspapers. By the age of eighteen he was a commission and insurance agent. Having read about the Witwatersrand gold discoveries, he took ship to South Africa in 1894, joining the Equitable Insurance Company (an American concern) in Johannesburg, and becoming a highly successful insurance salesman. Within less than two years Schlesinger rose from a state of abject poverty to affluence, earning more than £1 000 a month commission by tirelessly travelling the length and breadth of the country selling policies, and in this way acquiring an extensive knowledge of South Africa.

Just before the outbreak of the Second Anglo-Boer War (1899-1902) the Equitable made him its regional manager in Ireland. He returned to Johannesburg at the end of hostilities to launch a property development enterprise, the African Realty Trust, which, until 1904, developed new residential suburbs in Port Elizabeth (Mount Pleasant) and Johannesburg (Orange Grove, Houghton, and Killarney) by giving salary-earners an opportunity to buy their own homes on an instalment basis.
At the end of 1904 Schlesinger founded his own insurance company, the African Life Assurance Society, which, during its first year of business, sold 2 274 policies valued at more than £I million. As the managing director Schlesinger personally organized the whole company from board-room to stationery cupboard, and coached all canvassers and agents. In 1905 he bought the Robinson South African Bank (founded by J. B. Robinson), which had run into financial difficulties, converting it into the Colonial Banking and Trust Company, which specialized in small loans to businessmen. In 1911 he established the African Guarantee and Indemnity Company, which handled all types of insurance finance.
Schlesinger first entered the entertainment business in 1913 with the purchase of the Empire Theatre in Johannesburg for £60 000. He rapidly converted a near-bankrupt enterprise into a flourishing concern, African Consolidated Theatres, and provided a centralized organization for the distribution of films and variety acts on a nationwide basis. A,subsequent subsidiary enterprise was African Film Productions, with its weekly African Mirror , considered to be the oldest news-reel in the world. During the twenties it was Schlesinger who sponsored the country’s first chain of radio stations, forming the African Broadcasting Company (1930), from which, in 1936, the South African Broadcasting Corporation evolved as a government undertaking.
Schlesinger also interested himself in commercial farming, and at Langholm, near Grahamstown, he pioneered several large pine-apple plantations, establishing a canning factory in Port Elizabeth. At Kendrew, near Graaff-Reinet, he embarked on an elaborate programme of citrus cultivation under intensive irrigation, a project which failed, however, owing to the technical inadequacies of the catchment area. It was in Zebediela, in the northern Transvaal, that he developed what became the largest single citrus estate in the world.
By the early thirties, on the basis of the spectacular success of the insurance companies he had founded, Schlesinger had come to own an imposing network of cinemas and theatres, besides holding major interests in retail concerns, banking, advertising, hotels, catering, amusement parks, agriculture, canning, diamond cutting and newspapers, besides being chairman of more than eighty companies.
Of stocky stature, always immaculately dressed, and an avid reader of miscellaneous literature, ‘I.W.’, as his associates and staff called him, was a man of tremendous physical energy who liked working long hours, especially on ventures that provided a test for his salesmanship and astonishing business acumen. He enjoyed the excitement of launching new enterprises, which he planned down to the minutest detail. He maintained close personal control over all his companies, and hated delegating authority.
Schlesinger married Mabel May, a well-known actress of Johannesburg. Their only son, John Samuel Schlesinger (*1923), was educated at Michaelhouse, Natal, and Harvard University, U.S.A., and took over the vast Schlesinger organization in 1949, on the death of his father.
During the last years of his life Schlesinger was crippled with arthritis. Despite his affection for his adopted country, he never gave up his American citizenship. He was buried at Zebediela, in the northern Transvaal.
