After Franfurt lost its Free State status, Johann Hector Rössler (1842-1915) assumed control of the privatized Frankfurt refinery which his father had managed/owned; his younger brother Heinrich (1845-1924) was then completing his dissertation on the double cyanides of Platinum and Palladium.  As retailers for Johnson-Matthey, their refining business presumably shipped back small amounts of Platinum slag to London for re-purification and manufacture.
