Ringsdorf's major research works deal with the self-assembly of polymers into functional aggregates, where 'the whole is more than the sum of its parts'. He is known for being the first to propose covalently bonding drugs to water-soluble polymers.[1]
Ringsdorf was born in Gießen, People's State of Hesse in 1929.[2][3]
Ringsdorf died on 20 March 2023, at the age of 93.[4]
Ringsdorf took undergraduate studies in Chemistry, Politics and Geology at the universities at Frankfurt, Darmstadt and Freiburg.[2][3]
In 1956, Ringsdorf wrote his master's thesis under Hermann Staudinger and, in 1958, wrote his doctoral dissertation under Staudinger and Elfriede Husemann. He was Staudinger's last student.[5]
