For 10 points, give the common last name of these American chemists with first names Robert and Elias.
One man with this last name built a vacuum line used to separate germanium hydrides, and headed the lab in which Hoogsteen pairing was discovered. That man was the first to determine the structure of glycine and alanine, and co-names a molecular model in which atoms are represented as spheres with radii proportional to van der Waals radii along with Pauling and Koltun. A second man with this last name co-names an enantioselective reduction of ketones via the namesake catalyst along with Bakshi and Shibata, and co-names a reaction in which terminal alkynes are created from aldehydes along with Fuchs. He also developed a method in which molecules are dissected into smaller and smaller parts until they are broken down into simple building blocks, a technique he termed "retrosynthetic analysis."
