George Pearson Glen Kidston (23 January 1899 – 5 May 1931) was an English record-breaking aviator and motor racing driver.

Kidston was a member of the well known Bentley Boys of the late 1920s, and possibly the wealthiest of that already wealthy set. His father, A.G. Kidston, was a grandson of the original A.G. Kidston who was a metal and machinery merchant in Glasgow with interests in the Clyde Shipping Company, local solicitors, accountants and banking interests amalgamated into the Clydesdale Bank. Andrew Bonar Law MP was a Kidston, by his mother, and Chancellor of the Exchequer during World War I, being briefly Tory Prime Minister in the year of his death 1923 ("The Forgotten Prime Minister, the life and times of Andrew Bonar Law, 1858-1923 (1955) "). Kidston was one of the four, core Grosvenor Square-based Bentley team drivers, whose day-long parties passed into contemporary legend.

A former Lieutenant Commander in the Royal Navy, he was torpedoed twice (in the consecutive sinkings of HMS Aboukir and Hogue) in the same morning during the action of 22 September 1914 against German submarine U-9 under the command of Commander Otto Weddigen as the fleet manoeuvred. Following repatriation he served in the dreadnought HMS Orion, with the British Grand Fleet at the Battle of Jutland, running gunnery orders on open deck under direct enemy fire. Kidston grasped submarine tactics and served on several leading-edge British submarines, including the notorious X1, which he served on (Source: Family) in North Sea trials. During the trials the X1 embedded itself in the seabed as its gauges were faulty, but was freed after a dangerous period on the sea bed. In December 1926 he received command of the H-class submarine, the Beardmore-built H24, built at Portsmouth. Away from his duties as a submariner, he was an early pioneer of naval flight (Source: Family).

Glen Kidston competed in numerous motor races including prestigious events such as the Monte Carlo Rally, Isle of Man TT motorcycle races, and Shelsley Walsh hillclimb. As a naval amateur he raced a Sunbeam motorcycle up the hill climb in Hong Kong and conducted speed trials on the sands, bringing the bike with him in his submarine which was patrolling the China Station (Source: Family). Kidston entered the 1929 Irish Grand Prix Éireann Cup at Phoenix Park but was narrowly beaten by the Alfa Romeo of former Russian Imperial Guard officer Boris Ivanowski. This was achieved at the expense of Britons Glen Kidston and Henry Birkin, whose Bentleys were second and third respectively. He also owned and raced the first Bugatti in the UK and entered the Le Mans 24-hour race in 1929 and 1930. On the second occasion he won the race, driving a Bentley Speed Six in partnership with Woolf Barnato, with the Bentley team delivering an epic 1-2-3-4 victory.

In 1929 Kidston was travelling from Croydon to Amsterdam in a German airliner. 21 mins into the flight he sensed an imminent crash and assumed the safety position, likewise assisting his fellow traveller Prince Eugen von Schaumberg-Lippe. On impact, Kidston kicked out the fuselage whilst alight all over and doused himself in the wet grass. He re-entered the burning wreck to save the badly burned Prince who subsequently died; the flames prevented him assisting others. Kidston fought through a mile of wood at night to summon help. As he flagged a motorist down, his clothes were still smoking. He rang the details to Croydon Airport personally before flying for a brief flight to rebuild his nerve. He was then hospitalised with extensive burns. Kidston was the sole survivor. (Source: Canberra Times Friday 8 November 1929, p. 5).

Kidston was a renowned big game shot and travelled on pioneering safaris in remote Kenyan districts. Films of these expeditions, of his early naval and other aviation and Bentley teamwork are held at the British Film Institute due to their quality and pioneering footage.

In April 1931, Glen Kidston completed a record breaking flight from Netheravon, Wiltshire to Cape Town, South Africa. He completed the journey in just 6½ days, flying his own specially adapted Lockheed Vega monoplane and averaging 131 mph. However, Kidston was never to make the return trip. After earlier near misses in aeroplane, motorcycle, speed boat and even submarine accidents, Kidston was killed, only a year after his Le Mans triumph when his borrowed de Havilland Puss Moth broke up in mid-air while flying through a dust storm over the Drakensberg mountains. A memorial to him stands to this day at the place where his aircraft crashed, being an aluminium propellor set in stone to warn passing aviators. His gravestone at St. Peter's in Glasbury-upon-Wye on the Welsh borders, his childhood home, reads "Time and tide wait for no man", with a sun dial (Source: Family).

News of Kidston's death broke in the London evening papers and both Margaret Whigham, later Duchess of Argyll, and Barbara Cartland, both amongst Kidston's lovers, claim in their memoirs to have fainted on leaving the theatre and seeing the headlines. Cartland named her first son Glen in his memory. The Hollywood femme fatale Pola Negri is also reputed to have known Kidston.

He married Nancie Miriel Denise Soames in 1925 and had a son, Archibald Martin Glen (1927–1978).
