He held professorships at various universities, contributing significantly to the nomenclature of the field. Graebe's collaboration with Liebermann led to the first synthesis of the economically important dye alizarin, marking a milestone in the dye industry. His research on colorants and structural theory, including the introduction of nomenclature for naphthalene ring substitution, furthered the field's development. Graebe's mentoring of students and contributions to chemical synthesis have left a lasting impact on chemistry.

Wilhelm Körner, also known as Guglielmo Körner, was a German chemist known for his work on aromatic compounds and botanical studies. He studied chemistry at Giessen and later became an assistant to Kekulé in Ghent. Körner then moved to Palermo to work with Stanislao Cannizzaro. In 1870, he accepted a professorship in organic chemistry at the University of Milan, where he remained until his retirement in 1922. Körner's research and teaching contributions spanned over five decades, illustrating his significant impact in the field of chemistry.
