Frank L. Lambert, (born July 10, 1918 in Minneapolis, Minnesota) is a Professor Emeritus (Chemistry) of Occidental College, Los Angeles CA.. He is known for his successful advocacy of deleting the definition of thermodynamic entropy as “disorder” from U.S. general chemistry texts and its replacement by viewing entropy as a measure of molecular energy dispersal. [1-7]
Fortunate to be awarded a scholarship to Harvard in the competition initiated by President James Bryant Conant “to increase the geographical diversity of Harvard undergraduates” in 1935, Lambert had the privilege of being in the class of 1939. (Students were assigned to bench spaces alphabetically in chem labs. He was next to a student named Bill Knowles. In 2001 William S. Knowles won the Nobel Prize in Chemistry.) Mistakenly thinking that he could shorten his grad school work, Lambert as a senior was admitted to Kistiakowsky’s thermodynamics course for graduate students. Its difficulty sealed his decision to become an organic chemist rather than a physical chemist. However, he graduated with honors in 1939.
Applying to the University of Chicago because of the possibility of working on then-novel free-radical chemistry under the direction of the distinguished organic chemist, Morris S. Kharasch, Lambert learned that Chicago rejected any prior courses in thermo and required its own ‘brand’. Fortunately, however, Kharasch accepted Lambert in his research group and in 1942 Lambert received the Ph. D. with a dissertation on the effect of metallic halides on some Grignard reactions. Two articles resulted from it,[8,9] initiating his 66-year span of publication in peer-reviewed scientific journals.[8 - 6]
Lambert joined the Edwal Laboratories in Chicago after receiving his doctorate. His projects involved syntheses of rare and custom chemicals (primarily for pharmaceutical companies) until he was drafted into the Medical Department of the U.S Army in 1944. He served in the Philippines but was granted early discharge in 1946 because Ringwood Chemical, a subsidiary of Edwal, requested his services to speed the development of new nutrients for penicillin production by Pfizer. A second major assignment was aiding the first ton-lot production of Lindane in the US, an effective pesticide whose synthesis involved thousands of gallons of benzene, but one that is now banned in 52 countries because of its broad toxicity.
An unusual teaching opportunity at the University of California, Los Angeles, was offered to Lambert for 1947-48. He and another organic chemist were appointed instructors, with one to be retained for a tenure track position in 1948. His duties involved directing graduate student assistants in general chemistry for one semester and teaching organic chemistry the second. For thirty-nine years, he was mildly disappointed that UCLA had decided to retain the other instructor – until the other man, Donald J. Cram, received the Nobel Prize in Chemistry in 1987. UCLA had chosen correctly.
Occidental College needed an organic chemist as an assistant professor in its chemistry department in 1948 and Lambert accepted the position, becoming a full professor in 1956. His initial educational publications described innovations for organic chemistry lectures: The design and construction of the first large-scale Fisher-Hirschfelder-Taylor molecular models (one inch to 10 nm) formed by precise cutting and joining Styrofoam balls.[10, 11] Large Styrofoam models of atomic and molecular orbitals were then found to be equally readily constructed.[12] Finally, he developed a novel mode of introducing students to atomic orbitals via simple ‘slicing’ of wave patterns (analogized in Styrofoam) and the details were published for the use of chemistry instructors world-wide.[13]
In teaching organic chemistry, Lambert developed a procedure of ‘lecture-less’ instruction. Students were given his outline of the major (and trivial/ignorable) points in the textbook for the class meetings of the next week. Thereby, the classes could consist primarily of back and forth between the students and Lambert, emphasizing only the hard or ‘tricky’ portions of the assigned text. He called it the “Gutenberg Method” because, obviously, there had been movable type for textbooks for centuries and most organic texts were adequate repositories of information. “Why should the instructor present a boardful of elegantly organized material with answers by the score to questions that the students have not asked?”
Unknown to Lambert before the page proof was sent him, a presentation of his “Gutenberg Method’ at a National American Chemical Society meeting in 1962 was selected by the editor of the Journal of Chemical Education for an editorial on effective teaching[14] Most significant, Robert T. Morrison, co-author of the organic chemistry textbook that changed organic texts after 1959[15] extolled the “Gutenberg Method” in a 1986 publication[16] that Lambert did not learn about until 2000.
More recent educational publications by Lambert dealt with the humane importance of thermodynamics and chemical kinetics – an important viewpoint rarely if ever before brought to adults who are not science-oriented nor to beginners in chemistry. The first in 1996, “Shakespeare and Thermodynamics: Dam the Second Law!”[17], admittedly limited reactions to exothermic oxidation such as the burning of paper and wood or shiny iron rusting. But this use of ‘before’ and ‘after’ energy levels permitted the introduction of the concept of activation energies as “dams”, desirable obstacles to undesirable second law predictions of reactions such as forest fires or rapid oxidation of our biosubstances. Extending the pattern to simple breakage of solid objects – where there is no thermodynamic change, but the fact that exceeding a given load (an “Eact solid”) results in instant fracture -- allows a useful generalization: It is such obstacles (Eact and Eact solid ) that generally protect us from undesirable processes. Things do not usually “go wrong” in our immediate physical world and the usual “dams” to undesirable occurrences are activation energies. Finnegan’s Law is a far more accurate predictor of what happens in our world than Murphy’s. (Finnegan’s Law? “Murphy’s Law usually isn’t true.”)
Two related articles “Why Don’t Things Go Wrong More Often? Activation Energies: Maxwell’s Angels, Obstacles to Murphy’s Law”[18] and “Chemical Kinetics: As Important As The Second Law of Thermodynamics?”[19] brought the preceding ideas to the attention of chemistry professors and students.
Lambert’s research in the synthesis and polarography of organic halogen compounds, always designed for undergraduate collaboration, resulted in a novel halogenation synthetic method[20] that became widely cited. In polarography, he and his students achieved the highest negative reduction potentials at their time, resulting in the first reduction of chlorinated aromatic compounds[21] and the first complete reduction of CCl4[22] This expertise provided the necessary techniques for determining the quantitative correlation of the reduction of 24 alkyl bromides with Taft polar constants[23] – a remarkable span that Professor Corwin Hansch has stated to be the largest of more than 6000 such correlations in his QSAR text[24].
Joining a chemistry faculty of three at a relatively unknown college in 1948, as faculty numbers and facilities improved, Lambert worked together with his colleagues to develop an unusual department. The summer student research program (aided by the first National Science Foundation Grants for any college for which he applied in 1959, and by similar applications for subsequent summers) has grown many-fold to be consistently among the three or four largest collegiate programs in the United States. (This size is only possible because of extreme devotion to student research by previous and current faculty and a chemistry building with greater than usual space for undergraduate research for which Lambert was the principal departmental planner and construction supervisor.) For two decades recently, Occidental had more chemistry graduates annually than other West Coast colleges and usually exceeded two nationally prominent California universities. Probably no other US college has had three Rhodes Scholars from chemistry in a decade as did Occidental and only a few have received as much research support in grants and awards in recent years.
Selected by a faculty committee in 1961, Lambert was the first scientist at Occidental to be a Faculty Award Lecturer, the faculty’s highest award for teaching and national scholarship. In 1968, selected by vote of the senior class, he became the first recipient of a now-traditional student honor for outstanding teaching, the Loftsgordon Award.
After his retirement from Occidental College in 1981 Dr. Lambert joined the staff of the J. Paul Getty Museum (located then in the present Getty Villa in Malibu) as the first permanent scientific advisor to the Museum, working primarily with the Antiquities Conservation Department. When the bequest from the Getty estate was received by the Museum, he became the principal aide to the Scientific Research Director of the new Getty Conservation Institute in 1983. As ‘GCI’ grew to have some fifteen scientists on staff, he continued research[25], principally on problems of maintaining low-oxygen atmospheres in sealed display cases, and aided in the writing of three books[26,27,28] until 2002.
Fortunately, responsible only for organic chemistry classes at Occidental, Lambert never had to teach general chemistry. Unfortunately, for a new course for non-science majors that he had to teach for several years, he chose a text that forcefully presented entropy as “disorder” (but otherwise well developed simple chemical kinetics and thermodynamics). Two decades after that period and at the end of his Getty career, he began to think about the serious problem of defining a scientific concept, entropy, by such a non-scientific measure as “disorder”.
The initial result was a 1999 article[1] pointing out that macro “disorder” – mixed-up objects in dorm rooms or messy desks or shuffled cards -- had nothing to do with thermodynamic entropy. This was followed in early 2002 by an article that collected comments from scientists and common examples showing the failure of “entropy as disorder”.[2] Included therein were Lambert’s first statements about a scientific description of entropy increase “as the result of the dispersal of energy in space generally and the occupancy of more microstates technically…”. This was further developed in late 2002 [4] where a simple statement of the second law was “Energy associated with macro objects or with molecules disperses, spreads out, dissipates from being localized if the dispersal process is not hindered”. The online version of “Entropy Is Simple, Qualitatively” [http://www.entropysite.com/entropy_is_simple/index.html] then adds from a 2007 article[6] : “This statement of the second law is not complete without identifying the overall process as an increase in entropy including the fact that spontaneous thermodynamic entropy change has two requisites: The motional energy of molecules that most often enables entropy change is only actualized if the process makes available an increased number of microstates, a probability requisite. Thereby, thermodynamic entropy change is clearly distinguished from information ‘entropy' by having two essential requisites, energy as well as probability.” (Information ‘entropy’ has only one requisite, probability.)
Lambert’s penultimate article[6] showed that “configurational/conformational/positional” entropy is essentially an artifact of statistical mechanics: the process of counting locations or arrangements in three-dimensional space – translated to phase space – actually is equivalent to the count of momenta in phase space, i.e., a count of energetic microstates. That is why the results of a Boltzmann calculation of the spontaneous entropy change in a doubling of volume of an ideal gas (e.g., expansion to an evacuated bulb in the stereotypical two-bulb system) is equal to a Clausius calculation via reversible compression to the original volume, R ln V2/V1. Entropy change is entropy change, whether isothermal (“positional”) or thermal.
The results of Lambert’s articles are given by comparing Note 7 with Note 3 (below). . His five websites (see “Links” at [http://www.entropysite.com], that are linked to by scores of high schools and colleges, receive some 20,000 readers from over 100,000 hits per month. His writings are recommended reading in science curricula at such schools as Colorado College, Bryn Mawr College, University of Pennsylvania, Michigan State University, Trinity College, Perth, and the University of Oklahoma.

“The Second Law of Thermodynamics”, http://www.secondlaw.com. A conversational, no-math, no-equation introduction to the subject for all levels of students, including adults who are not in science, but especially for beginners in chemistry ..
“Entropy and the Second Law of Thermodynamics”, http://www.2ndlaw.com/ . A five-part introduction to the second law and entropy from a micro (molecular behavior) standpoint.
The first part develops the ideas of molecular translational, rotational and vibrational motion and also quantized energy levels and microstates without math or quantum mechanical details.
The second is almost a repetition of an introduction to activation energy in secondlaw.com
The third part develops different forms of activation energies and introduces the transfer of energy from one exothermic process to facilitate a coupled endothermic process.
The fourth deals with the second law and evolution – energetically, the second law favors evolutionary processes (and coupled energy transfers can facilitate the synthesis of higher energy substances). Thus, the claim that the second law ‘forbids’ or makes evolution impossible is false
The fifth “Entropy and Gibbs free energy is only for chemistry students.
“Entropy Is Simple – If We Avoid the Briar Patches!”, http://entropysimple.com/ A description of the second law’s implications for ecology, and its benefits for humans. Less informal than the conversational secondlaw.com and thus better for adults.
“Shakespeare and Thermodynamics: Dam The Second Law”, http://www.shakespeare2ndlaw.com/ A site primarily for students or adults in the humanities and the arts. A readable summary of what C. P. Snow should have said about the second law and activation energies to his audiences when he mentioned thermodynamics. Some of the ideas in secondlaw.com, but omitting any development of entropy.
