● Early Life and Education

James Alfred Ewing was born on March 27, 1855, in Dundee, Scotland, to a family of modest means. He attended Edinburgh Academy and later enrolled at University of Edinburgh, where he studied physics and mathematics under the guidance of Peter Guthrie Tait and William Thomson (Lord Kelvin). During his time at University of Edinburgh, Ewing was exposed to the works of prominent scientists, including James Clerk Maxwell and Hermann von Helmholtz. He also developed an interest in engineering and materials science, which would later become a significant focus of his research. Ewing's education was further influenced by his interactions with other notable figures, such as William Rankine and Fleeming Jenkin.

● Career

Ewing's career spanned several decades and took him to various institutions, including University of Cambridge, University of Tokyo, and University of Edinburgh. In 1878, he was appointed as a lecturer in mechanical engineering at University of Cambridge, where he worked alongside Lord Rayleigh and J.J. Thomson. During his time at University of Cambridge, Ewing became interested in seismology and began to study the properties of earthquakes and seismic waves. He also collaborated with other prominent scientists, including John Michell and Charles Darwin. In 1886, Ewing was appointed as the first professor of mechanical engineering at University of Tokyo, where he played a significant role in establishing the university's engineering program. He worked closely with Japanese scientists, including Fujisawa Ichiro and Takahashi Yoshio, to develop new technologies and infrastructure.
