Adrien Albert AO (19 November 1907 – 29 December 1989) was a leading authority in the development of medicinal chemistry in Australia. Albert also authored many important books on chemistry, including one on selective toxicity.

His father, Jacques Albert, was a businessman in the music industry, and took a bride many years his junior; Mary Eliza Blanche. Albert had two much older half brothers, stemming from his father's previous marriage. After a few years, Jacques died, and so, Adrien Albert was raised by his mother and another relative. Albert attended schools in Randwick and Coogee, but soon settled into the Scots College in Sydney where he excelled in both music and science. He graduated in 1924.

He was awarded BSc with first class honours and the University Medal in 1932 at the University of Sydney. He gained a PhD in 1937 and a DSc in 1947 from the University of London. His appointments included Lecturer at the University of Sydney (1938–1947), advisor to the Medical Directorate of the Australian Army (1942–1947), research at the Wellcome Research Institute in London (1947–1948) and in 1948 the Foundation Chair of Medical Chemistry in the John Curtin School of Medical Research at the Australian National University in Canberra where he established the Department of Medical Chemistry. He was a Fellow of the Australian Academy of Science. In 1939 he was a foundation member of the Drugs sub-committee of the Australian Association of Scientific Workers.^[1]

Albert was a scholar of heterocyclic chemistry.^[2] He authored Selective Toxicity: The Physico-Chemical Basis of Therapy, first published by Chapman and Hall in 1951.

Albert was made an Officer of the Order of Australia (AO) in the 1989 Australia Day Honours for "services to medical chemistry, particularly in the fields of teaching and research".^[3]

The Adrien Albert Laboratory of Medicinal Chemistry at the University of Sydney was established in his honour in 1989.^[4] His bequest funds the Adrien Albert Lectureship, awarded every two years by the Royal Society of Chemistry.^[5] The Royal Australian Chemical Institute established the Adrien Albert award (Archived 19 February 2017 at the Wayback Machine) in his honour.
