WebThe use of multiple crystals in ladder and lattice configurations was proposed in the late 1920’s and in 1934 Walter P. Mason published the results of his work on crystal filters which were developed for use in frequency-division-multiplex telephone systems. In Mason’s paper he describes a “narrowband” design which is useful for ... WebThe idea that atoms form covalent bonds by sharing pairs of electrons was first proposed by G. N. Lewis in 1902. It was not until 1927, however, that Walter Heitler and Fritz London showed how the sharing of pairs of electrons holds a covalent molecule together. The Heitler-London model of covalent bonds was the basis of the valence-bond theory.
