This patent makes reference to the German priority date 1912-02-13.


This original does give "Michaed", but there is a "Michael Roukawischnikoff", in the same location, filing other patents, fairly contemporaneously. Also, there are variable conventions on transliteration from Russian. There may be more on him. For now we will defer to the "Michael Rukawischnikoff" which appears in our slightly earlier French data.
