Lech Paszkowski matriculated in 1938, but before he could pursue his interest in history he was caught up in World War II. After arriving in Australia, he worked with the Melbourne City Council as an electrical mechanic for many years while also studying journalism, becoming an Australian correspondent for magazines published in Brazil, England, and France, and helping to set up the Polish press and newspapers in Australia.
Writing as a biographer and historian, particularly of Polish Australians, his biographies of Dr John Kubary, Dr Jan Danysz and William Blandowski appeared in the journal Australian Zoologist. He has contributed articles to the Australian Dictionary of Biography and the Polski Slownik Biograficzny (Polish Dictionary of Biography) . His work is also found in Polish People and Culture in Australia (1985), The Australian People : an encyclopaedia of the nation, its people and their origins (1988 and 2001), and the Polish journal Archiwum Emigracji. Paszkowski was interviewed for the Polish-Australian Oral History Project in 1997 for the Australian National Library. He has written much on the explorer Strzelecki, including editing Clew's account Strezelecki's ascent of Mount Koscuiski, 1840 (1973).
He has been a member of the Quill Club Writers of Australia, the Royal Historical Society of Victoria and the Union of Polish Journalists (London).
