Royal Observer Corps
In 1929 the control of the Observer Corps passed from the county police forces to the Air Ministry, although Chief Constables retained responsibility for personnel and recruitment matters. 1 March 1929 saw the establishment of the new "Headquarters of the Observer Corps" at Hillingdon House, RAF Uxbridge in the west of London, and Air Commodore Edward A D Masterman CB CMG CBE AFC RAF (Rtd) was appointed as the first commandant of the Observer Corps. "Air Cdre" Masterman held this appointment until his retirement on 1 March 1936, and was succeeded by Air Commodore Alfred Warrington-Morris CG CMG OBE AFC RAF (Rtd), who would lead the Observer Corps through the critical period during the Second World War which saw the RAF emerge bruised but victorious following the Battle of Britain of 1940.
City Observatory
In 1812 the observatory was handed over to the Edinburgh Astronomical Institution, which opened its popular observatory in the Gothic Tower. In 1818 work began on the Playfair Building. Designed by William Henry Playfair this was to become the scientific observatory of the Institution. Following a loyal address to George IV in 1822 this became the Royal Observatory. Again the funds proved insufficient, so that the purchase of instruments and the employment of an observer depended on funding from the Government. After much delay the instrumentation was completed in 1831 with delivery of the transit telescope. Fraunhofer had made the lens, but after his death it fell to Repsold – and after his death to Repsold's son – to complete and install the instrument.
