Endel Lippmaa (15 September 1930 – 30 July 2015)[1] was an Estonian scientist, academician, politician, and twice government minister in 1990–1991 and 1995–1996.
Lippmaa was founder and chairman of the Science Council of the National Institute of Chemical Physics and Biophysics.
[2] During Lippmaa's time working in physics, he wrote a paper on "Structural studies of silicates by solid-state high-resolution silicon-29 NMR,".
[3] This paper, now highly regarded, demonstrated in 1980 that high-resolution NMR spectroscopy could be applied profitably to inorganic samples, not just organic or biological ones.
In 1989, in the newly elected Soviet Congress he become best known for his work in uncovering and denouncing of the crucial documents of the 1939 Nazi-Soviet Pact which in June 1940 had resulted in the Stalinist Soviet Union's military invasion, occupation and illegal annexation of three Baltic countries: Estonia, Latvia and Lithuania.
