For 10 points, give this last name of Nobel Prize winner Emil, who names an esterification and a projection.
A scientist with this last name investigated pyrrole chemistry, which led him to the syntheses of pyrrole pigments like bilirubin and heme, for which he won the 1930 Nobel Prize. Another scientist with this last name accidentally discovered phenylhydrazine and also developed a total synthesis of caffeine. That scientist with this last name established the stereochemistry of (*) sugars and names a method along with Kiliani to synthesize monosaccharides, as well as an indole synthesis. Removing water via a Dean-Stark trap improves the yield of an acid-catalyzed reaction of carboxylic acids with alcohols named for him. That man also gives his name to molecular diagrams consisting of horizontal and vertical lines that indicate atoms pointing toward or away from the viewer, respectively.
