Alexander Wood (3 May 1879 – 1 April 1950)^[1] was aScottishphysicist who worked as researcher and university lecturer in the field ofacoustics andexperimental physics.^[2]

Son of Sir Alexander Wood of Partick, he was born in Scotland and educated atGlasgow University and obtained a doctorate in 1907. That very year he went toEmmanuel College, Cambridge, where he became a fellow and tutor.

At the fiftieth anniversary of the discovery of the electron, Wood lectured on the work and history of theCavendish Laboratory^[3] of which he was a well-known and active member.^[4] Future NobelistGeorge Paget Thomson, who attended Wood's lectures of physics, would comment later: "these were outstanding both in material and exposition, and impressed me greatly."^[5] Similarly,Alan Lindsay Mackay, who was Wood's student, mentioned him as one of his great professors and someone whose lectures were full of demonstrations.^[6] In addition, scientistCharles Alfred Coulson spoke of Alex as one of his three major influences,^[7] andLawrence Bragg corresponded with him asking for help in his research.^[8][9]

As a pupil ofLord Kelvin (William Thomson) at the University of Glasgow, Wood acquired some of his religious practices as the habit of praying before lecturing.^[10] He was a devout Christian and active member of theChurch of Scotland in Cambridge, worshiping regularly atSt Columba's Church in Downing Street and held Bible lessons and spoke about the relation between science and religion.^[11]

In addition, along withKees Boeke andHerbert Gray, during theWorld War I he was a member of theFellowship of Reconciliation, a group of religious pacifists.;^[12] at the time of conscription he was aconscientious objector. He was a leading member of thePeace Pledge Union, serving as Chair, 1940–46, and was also active in theNational Peace Council. After his death, theologianCharles E. Raven wrote a biography of the physicist entitledAlex Wood: the man and his message (1952).

In the1929 general election Wood stood as theLabour Party candidate for the two-memberCambridge University constituency, coming bottom of the poll with 1,463 votes (9.1%) at the first count.^[13] He then stood on three occasions as a Labour candidate for theCambridge seat: in the1931 and1935 general elections, and at the interveningby-election in February 1934.^[14][15] The headquarters of CambridgeConstituency Labour Party in Norfolk Street are named after him as is Alex Wood Road in Arbury and the Alex Wood Care Home in Fortescue Road.^[16]
