A nice lot of three pieces by notable scientists includes GLENN T. SEABORG, Nobel Prize in chemistry, 1951 for the plutonium A-bomb. A.Ms.S. 1p. 4to., [n.p., n.d.], the first page of an essay titled "Our Energy Future", written in pencil signed in pen at top and reading, in small part: "...The traumatic impact of our energy crisis has provided us with a not too early recognition of the reality of boundaries in our energy supply...Fortunately we can foresee solution...implementation of a coherent and realistic natural energy policy...". With ARNO PENZIAS, Nobel prize winner in physics, A.Ms.S. 1p. 4to., [n.p., n.d.], regarding his research of the Pegasus cluster of galaxies for hydrogen live emission. In verso he writes: "...Note (first draft) written in 1964 (?) concerning an error that had been found in my doctoral thesis (published in 1962). Arno Penzias May 31, 1979". Together with KONRAD LORENZ and NIKOLAAS TINBERGEN, their signatures on a FDC honoring Wildlife Habitat, cancelled Reno, Jun. 26, 1981. Three pieces, very good.
