Professor Emeritus Anthony Addison is a direct descendent of the Australian school of Inorganic Chemistry, originated by Mellor, Nyholm, Sargeson, Dwyer, and others. Addison did his PhD in the UK, then studied Biophysical Chemistry with I.M. Klotz at Nothwestern University.

He was one of the original proponents of electrochemical techniques in inorganic chemistry, and has applied it, as well as magnetochemistry and EPR and other spectroscopies, to inorganic and biomolecular systems. He has taught these subjects at the bachelor degree and doctoral degree levels, as well as presenting elementary topics to over 8,000 first-year students.

He and his students explained the way in which the molecular environments of copper ions govern their electron-transfer properties relevant to biomolecules. His group's research, founded in molecular craftsmanship, has led to highly impactful ideas such as EPR/structure correlations, a standard non-aqueous electrochemical reference electrode, and the τ structure index, that enable other scientists to interpret and understand their own research results.

He has also been engaged for many years with colleagues in their professional societies' activities at the local, regional and national levels. With numerous US and international collaborators, he has brought together and empowered chemists who previously did not share any research connnections. He has hosted two Fulbright Foundation Fellows in his lab.
