with Sir Ernest and the Anglo American Corporation in Johannesburg, was of great help at all times.
On
the technological side, I had the privilege of frequent discussions
with the late Dr. Austen Bancroft. I must, in the same connexion, thank
particularly Mr. A. Royden Harrison and Dr. A. E. Waters, respectively
chief consulting engineer and consulting geologist of the Anglo
American Corporation.
As
regards Copperbelt affairs, I have benefited from discussions with the
late Mr. A. J. Brink, recently general manager of the Bancroft Mine,
with Mr. O. B. Bennett of the Rhokana Corporation, now Minister
Designate for the Federation in Washington, and with Dr. T. D.
Guernsey, formerly consulting geologist in Rhodesia of the Anglo
American Corporation. But I would make it clear that I have at all
times received the most willing aid and assistance from the officials
and staffs of the Anglo American Corporation group generally, and I
hereby extend my thanks. I have naturally made large use of the
resources of the Public Relations Department of the corporation, and
extend thanks to Mr. A. N. Wilson, public relations consultant to Anglo
American Corporation and De Beers Consolidated Mines, and to his
colleagues, especially to Miss E. P. A. MacDonald. Mr. Wilson has also
greatly helped on the technical aspects of the publication of this
book. The officials of the Northern Rhodesia and of the Transvaal and
Orange Free State Chambers of Mines have been most helpful throughout
the years during which this book was in preparation.
Messrs.
Morgan, Grenfell and Company of London (through the kind
instrumentality of Lord Rennell of Rodd) allowed me to examine their
records of correspondence with Sir Ernest Oppenheimer, and also
memoranda and documents relating to De Beers, Anglo American
Corporation and Copperbelt affairs. Messrs. N. M. Rothschild and Sons
were kind enough to help on one or two points relating to C. J. Rhodes.
The Standard Bank of South Africa also furnished me with documentary
material relating to the earlier days of the diamond industry, and my
thanks go to Mr. J. A. Henry of Cape Town and to Mr. A. McK. White of
Pretoria, both of the Standard Bank, for making the necessary
arrangements. The late Lord Robins of Rhodesia and Chelsea, president
of the British South Africa Company, was good enough to read in proof
chapter VII on the 'Northward Expansion' and to make some comments.
In
the (European) summer of 1957 I was given the opportunity of visiting
the traditional centres of diamond cutting in Europe—Antwerp
