Rudolph Marcus enters Baron Byng High School where he receives an excellent education.

Rudolph Marcus receives his Ph.D. from McGill University.

Marcus enters the Caltech as the Arthur Amos Noyes Professor of Chemistry. Nowadays research in Marcus’s group involves analyses and theories of a wide range of phenomena in chemical kinetics and in related processes. His team focuses on formulating theories to explain new and unexpected experimental results. Recent examples include the striking on-water catalysis of organic reactions, the fluorescent intermittency of semiconductor nanoparticles (quantum dots) and the study of enzyme catalysis.

Oscar K. Rice accepts Marcus at University of North Carolina. Here, he studies reaction rate theory and attends his first formal course in quantum mechanics. Three months after this preliminary study, Marcus begins his new life as a working theorist. He formulates a particular case of what is later entitled by B. Seymour Rabinovitch, RRKM theory, blending statistical ideas from the RRK theory of the 1920s with those of the transition state theory of the mid-1930s.

Marcus enters the University of Illinois. His interest in electron transfer continues, together with interests in other aspects of reaction dynamics, including designing "natural collision coordinates", learning about action-angle variables, introducing the latter into molecular collisions, reaction dynamics, and later into semiclassical theories of collisions and of bound states. In the astronomy library he studies classical mechanics, celestial mechanics, quasiperiodic motion and chaos.

Marcus receives the Nobel Prize in Chemistry "for his contributions to the theory of electron transfer reactions in chemical systems." Marcus theory describes, and makes predictions concerning, such widely differing phenomena as the fixation of light energy by green plants, photochemical production of fuel, chemiluminescence ("cold light"), the conductivity of electrically conducting polymers, corrosion, the methodology of electrochemical synthesis and analysis, and more.

Rudolph Marcus meets Dean Raymond Kirk of the Polytechnic Institute of Brooklyn at an American Chemical Society meeting in Cleveland. This meeting with Kirk is fundamental for Marcus's subsequent professional career. After a successive interview at Brooklyn Polytechnic, Marcus is hired by Kirk.

Marcus writes a brilliant paper on the transfer of an electron between two molecules. No chemical bonds are broken in such a reaction, but changes take place in the molecular structure of the reacting molecules and their nearest neighbours. This enables the electrons to jump between the molecules. Marcus finds simple mathematical expressions for how the energy of the molecular system is affected by these changes. He calculates the greatly varying rates measured for electron transfer reactions.

At the Polytechnic Institute of Brooklyn, Rudolph Marcus works as Assistant Professor (1951-54), Associate Professor (1954-1958) and Professor (1958-1964). Here, he undertakes an experimental research program on both gas phase and solution reaction rates, and he writes the 1952 RRKM papers. In 1955, Marcus begins his research on electron transfers utilizing his knowledge in electrostatics.

Rudolph Marcus spends a year and a half at Courant Institute of Mathematical Sciences at New York University auditing many courses.

Rudolph Marcus travels to Europe to works as Visiting Professor at the University of Oxford.

Marcus joins the Ph. D. program at the National Research Council of Canada. The photochemistry group is led by E.W.R. Steacie, an international figure in the study of free-radical reactions. Marcus takes advantages from Steacie’s research on gas phase reaction rates. In ‘48, Marcus and Walter Trost, a fellow Ph. D. at NRC, form a two-man seminar to study theoretical papers related to their experimental work. This experience leads Marcus to a second Ph.D., this time in theoretical work.

Rudolph Arthur Marcus is born in Montreal, Quebec, only child of Esther (née Cohen) and Myer Marcus. Since neither of his parents has a higher education, his academic "idols" are two paternal uncles who have received their M.D.'s at McGill University and a great-uncle, Henrik Steen (née Markus), an avid polyglot.

Rudolph Marcus works as Humboldt Awardee at the Technical University of Munich.

Rudolph Marcus attends McGill University under Dr. Carl A. Winkler, a specialist in rates of chemical reactions who studied under Cyril Hinshelwood at Oxford University. The passion and the enthusiasm of Winkler for the scientific research are exemplary for Marcus. At McGill University, Marcus takes a great quantity of mathematical courses, which later help him in creating his theory on electron transfer.
