Fleck, A. See Biographical Memoirs of Fellows of the Royal Society, Alexander Fleck, Baron Fleck of Saltcoats, 17, 242 154 (1971). He received his chemistry degree in 1911 at Glasgow and remained with Soddy as an assistant until 1913. He stayed in close contact with Soddy for another 2 years. He then moved on to industry and had a very successful career, serving as chairman of ICI from 1953-1960. His papers on radioactivity were all single author publications. 

Sir Alexander Fleck, 1889—. Author of many research papers on the radioactive isotopes. He proved the inseparability of uranium Xi and radioaetinium from thorium, of thorium B and actinium B from lead, of mesothorium 2 from actinium, of radium E from bismuth, and of radium A from polonium, and confirmed the discovery of uranium X3 by Faj ans and O. H. Gohring. Chairman of Imperial Chemical Industries, Ltd. See also ref. (1S7). 

The explanation of the radioactive isotopes was given independently by Alexander S. Russell, Frederick Soddy, and Kasimir Fajans in 1913 (90). With the aid of Alexander Fleck at Glasgow, who had devoted... 

Following a brief period with Haber, Georg Hevesy began work with Rutherford at Manchester in 1910. In 1913, he began work with Fritz Paneth in Vienna and conducted the first radiotracer experiments. At that time, it was known that one of the products of radium decay was a substance, having its own unique decay signature, called radium-D. Hevesy tried unsuccessfully to separate radium-D from lead. In 1913, Alexander Fleck (1889-1968), working with Soddy, found that radium-D, radium-B, thorium-B, and actinium-B were chemically inseparable from lead and were, therefore, isotopes of lead.

The first major shakeup came about following the 1957 Windscale incident. Eollowing the accident. Sir Alexander Fleck, who was then Chairman of ICI, was asked to draw up a series of reports addressing this structure of the AEA and of the various safety issues which the accident had highhghted.
