Gennadi Gennadiyevich Touretski (Russian: Геннадий Геннадьевич Турецкий, 17 July 1949 – 7 August 2020)[2] was a swimming coach, best known for training multiple Olympic gold medalists Alexander Popov and Michael Klim through the 1990s to early 2000s at the Australian Institute of Sport (AIS).

[4] Touretski was born in Leningrad (now Saint-Petersburg), USSR,[5] where he studied in more than one university, obtaining diploma in biomechanics, biochemistry, fluid mechanics and sports physiology.

[9] In Australia, besides Popov Touretski coached such stars as Michael Klim, Matthew Dunn, Ray Hass and Clementine Stoney, bringing them to Olympic and world cup medals.

[14] There, beside Swiss swimmers, he trains a few Ukrainian and Russian athletes, as well as his daughter Alexandra Touretski,[15] and Ian Thorpe who joined him in March 2011.

For example, he persuaded Klim to focus more on butterfly, as well as to change his crawling technique to the straight-arm "windmill style"; both decisions proved highly successful.
