JJ Shaw (1873-1948) was strongly influenced by John Milne in the early 1900s, and became a gifted amateur seismologist with his own observatory in West Bromwich. Further details of his observatory can be found in Report WL/99/13 on Historical Seismological Observatories in the British Isles. He is mainly remembered for his innovative engineering work in the development of the Milne-Shaw seismograph in about 1912-14 which became a world standard in the first half of the century. Many of JJ Shaw's papers were given by his son, HV Shaw, also a seismologist, to the University of Birmingham where they are held in the Lapworth Museum.
The NSA has made microfilm and paper copies of the seismograms and other relevant material.
