Josten and Taylor were inclined to take astrology and alchemy seriously, and held meetings of adepts, which I attended when technical advice was sought. It was suggested that alchemists of yore used nuclear reactors to transmute lead into gold, and I was asked to arrange an experimental test of the conjecture at Harwell.
From the current understanding of nuclear reactions it was clear that, while it might be remotely feasible to transmute gold into lead by successive neutron-captures and beta-decays over a long period, the converse transformation of lead into gold in a nuclear reactor was wholly impracticable.
A member of this Rosicrucian group, Gerard Heym, told me that Josten had discovered in the Paris Bibliotheque Nationale, in a medieval astrological manuscript, a new method of casting horoscopes, from which he prognosticated a sticky end for Hitler on 20 July 1944 - and the date was adopted for the attempt on Hitler's life.
After the failure of the coup, Josten was on the run from not only the Nazi powers but also some enraged survivors of the plot.
