One of the greatest American scientists of all time, he devised much of the theoretical foundation forchemical thermodynamics as well asphysical chemistry . As a mathematician, he invented vector analysis (independently ofOliver Heaviside ). It is in good part thanks to Gibbs that much of physical and chemical theory has since been exposited using vector analysis.Yale University awarded Gibbs the first AmericanPh.D. inengineering in 1863, and he spent his entire career at Yale. [*cite book | last = Wheeler | first = Lynde, Phelps | title = Josiah Willard Gibbs - the History of a Great Mind | publisher = Ox Bow Press | year = 1951 | id = ISBN 1-881987-11-6*] His thesis was entitled: "On the Form of the Teeth of Wheels in Spur Gearing."In 1901, Gibbs was awarded the highest possible honor granted by the international scientific community of his day, granted to only one scientist each year: the

Copley Medal of theRoyal Society of London , for being "the first to apply thesecond law of thermodynamics to the exhaustive discussion of the relation between chemical, electrical, and thermal energy and capacity for external work." [*[*] This is considered Gibbs's greatest scientific contribution.*http://www.1911encyclopedia.org/Josiah_Willard_Gibbs Josiah Willard Gibbs*] - Britannica 1911**Biography****Early years**Gibbs was the seventh in a long line of American academics stretching back to the 17th century. His father, a professor of sacred literature at the

Yale Divinity School , is now most remembered for his involvement in the "Amistad" trial. Although the father was also named Josiah Willard, the son is never referred to as "Jr." Five other members of Gibbs's extended family were named Josiah Willard Gibbs. His mother was the daughter of a Yale graduate in literature.After attending the

Hopkins School , Gibbs matriculated at Yale College at the age of 15. He graduated in 1858 near the top of his class, and was awarded prizes inmathematics andLatin .**Middle years**In 1863, Gibbs was awarded the first Ph.D. degree in

engineering in the USA from theSheffield Scientific School at Yale. He then tutored at Yale, two years in Latin and one year in what was then callednatural philosophy , now comparable to the natural sciences, particularly physics. In 1866 he went toEurope to study, spending a year each atParis ,Berlin , andHeidelberg , where he was influenced by Kirchhoff and Helmholtz. At the time, German academics were the leading authorities inchemistry ,thermodynamics , and theoretical natural science in general. These three years account for nearly all of his life spent outside New Haven.In 1869, he returned to Yale and was appointed Professor of

Mathematical Physics in 1871, the first such professorship in the United States and a position he held for the rest of his life. The appointment was unpaid at first, a situation common in Germany and otherwise not unusual at the time, because Gibbs had yet to publish anything. Between 1876 and 1878 Gibbs wrote a series of papers on the graphical analysis of multi-phase chemical systems. These were eventually published together in a monograph titled "On the Equilibrium of Heterogeneous Substances", his most renowned work. It is now deemed one of the greatest scientific achievements of the 19th century, and one of the foundations ofphysical chemistry . In these papers Gibbs appliedthermodynamics to interpret physicochemical phenomena, successfully explaining and interrelating what had previously been a mass of isolated facts."It is universally recognised that its publication was an event of the first importance in the history of

chemistry . ... Nevertheless it was a number of years before its value was generally known, this delay was due largely to the fact that its mathematical form and rigorous deductive processes make it difficult reading for anyone, and especially so for students ofexperiment al chemistry whom it most concerns... " (J J O'Connor and E F Robertson, " [*http://www.shsu.edu/~icc_cmf/bio/gibbs.html J. Willard Gibbs*] ")Some important topics covered in his other papers on heterogeneous equilibria include:

* The concepts ofchemical potential and free energy (available energy);

* A Gibbsian ensemble ideal, a foundation ofstatistical mechanics ;

* TheGibbs phase rule .Gibbs also wrote on theoreticalthermodynamics . In 1873, he published a paper on the geometric representation of thermodynamic quantities. This paper inspired Maxwell to make (with his own hands) a plaster cast illustrating Gibbs's construct which he then sent to Gibbs. Yale proudly owns it to this day.**Later years**In 1880, the new

Johns Hopkins University inBaltimore, Maryland offered Gibbs a position paying $3000. Yale responded by raising his salary to $2000, and he did not leave New Haven. From 1880 to 1884, Gibbs combined the ideas of two mathematicians, thequaternions ofWilliam Rowan Hamilton and theexterior algebra ofHermann Grassmann to obtainvector analysis (independently formulated by the British mathematicalphysicist andengineer Oliver Heaviside ). Gibbs designed vector analysis to clarify and advancemathematical physics .From 1882 to 1889, Gibbs refined his vector analysis, wrote on

optics , and developed a new electrical theory of light. He deliberately avoided theorizing about the structure of matter, a wise decision in view of the revolutionary developments insubatomic particle s andquantum mechanics that began around the time of his death. His chemical thermodynamics was a theory of greater generality than any other theory of matter extant in his day.After 1889, he worked on

statistical mechanics , laying a foundation and "providing a mathematical framework for quantum theory and for Maxwell's theories" [*J. J. O'Connor and E. F. Robertson, " [*] He wrote classic textbooks on*http://www.shsu.edu/~icc_cmf/bio/gibbs.html J. Willard Gibbs*] ".statistical mechanics , which Yale published in 1902. Gibbs also contributed tocrystallography and applied his vector methods to the determination ofplanet ary andcomet orbit s.Not much is known about the names and careers of Gibbs's students.

Gibbs never married, living all his life in his childhood home with a sister and his brother-in-law, the Yale librarian. His focus on science was such that he was generally unavailable personally. His

protégé E.B. Wilson explains: "Except in the classroom I saw very little of Gibbs. He had a way, toward the end of the afternoon, of taking a stroll about the streets between his study in the old Sloane Laboratory and his home -- a little exercise between work and dinner -- and one might occasionally come across him at that time." Gibbs died in New Haven and is buried inGrove Street Cemetery .**cientific recognition**Recognition was slow in coming, in part because Gibbs published mainly in the "Transactions of the Connecticut Academy of Sciences", a journal edited by his librarian brother-in-law, little read in the USA and even less so in

Europe . At first, only a few European theoretical physicists and chemists, such as the ScotJames Clerk Maxwell , paid any attention to his work. Only when Gibbs's papers were translated into German (then the leading language for chemistry) byWilhelm Ostwald in 1892, and into French byHenri Louis le Chatelier in 1899, did his ideas receive wide currency in Europe. His theory of the phase rule was experimentally validated by the works of H. W. Bakhuis Roozeboom, who showed how to apply it in a variety of situations, thereby assuring it of widespread use.Gibbs was even less appreciated in his native America. Nevertheless, he was recognised as follows:

* In 1880, theAmerican Academy of Arts and Sciences awarded Gibbs itsRumford Prize for his work inheat . [*cite book | last = Müller | first = Ingo | title = A History of Thermodynamics - the Doctrine of Energy and Entropy | publisher = Springer | year = 2007 | id = ISBN 978-3-540-46226-2*]

*In 1910, theAmerican Chemical Society , Chicago section, at the instigation ofWilliam A. Converse , established theWillard Gibbs Medal in his memory. [*[*]*http://membership.acs.org/C/Chicago/Gibbs_history.html Willard Gibbs Medal*] - Founded by William A. Converse in 1910During his lifetime, American colleges and secondary schools emphasized classics rather than science, and students took little interest in his Yale lectures. (That scientific teaching and research are a fundamental part of the modern university emerged in Germany during the 19th century and only gradually spread from there to the USA.) Gibbs's position at Yale and in American science generally has been described as follows:

"In his later years he was a tall, dignified gentleman, with a healthy stride and ruddy complexion, performing his share of household chores, approachable and kind (if unintelligible) to students. Gibbs was highly esteemed by his friends, but American science was too preoccupied with practical questions to make much use of his profound theoretical work during his lifetime. He lived out his quiet life at Yale, deeply admired by a few able students but making no immediate impress on American science commensurate with his genius." (Crowther 1969: nnn)

This is not to say that Gibbs was unknown in his day. For example, the mathematician

Gian-Carlo Rota , while casually browsing the mathematical stacks ofSterling Library , stumbled on a handwritten mailing list attached to some of Gibbs's course notes. It listed over two hundred notable scientists of his day, including Poincaré,Hilbert ,Boltzmann , andMach . One can conclude that Gibbs's work was better known among the scientific elite of his day than published material suggests.Gibbs' contributions, however, were not fully recognized until some time after the 1923 publication of

Gilbert N. Lewis andMerle Randall 's "Thermodynamics and the Free Energy of Chemical Substances", which introduced Gibbs's methods to chemists worldwide. These methods also became much of the foundation forchemical engineering .According to the

American Mathematical Society , which established the Josiah Willard Gibbs Lectureship in 1923 to increase public awareness of the aspects ofmathematics and its applications, Gibbs is one of the greatest scientists America has ever produced. [*[*]*http://www.ams.org/meetings/gibbs-lect.html Josiah Willard Gibbs Lectures*] -American Mathematical Society In 1945, Yale University created the

J. Willard Gibbs Professorship in Theoretical Chemistry , held until 1973 byLars Onsager , who won the 1968 Nobel Prize in chemistry. This appointment was a very fitting one, as Onsager, like Gibbs, was primarily involved in the application of new mathematical ideas to problems in physical chemistry, especially statistical mechanics. Yale's J. W. Gibbs Laboratory and J. Willard Gibbs Assistant Professorship in Mathematics are also named in his honor. On February 28, 2003, Yale held a symposium on the centennial of his death.

Hall of Fame for Great Americans .On

May 4 ,2005 , theUnited States Postal Service issued the "American Scientists" commemorativepostage stamp series, depicting Gibbs,John von Neumann ,Barbara McClintock andRichard Feynman .**Nobelists influenced by the work of Gibbs**The following individuals won a Nobel Prize in whole or in part by building on Gibbs's work:

*Johann van der Waals of the

Netherlands won the 1910Nobel prize in physics . In his Nobel Lecture, he acknowledged the influence on his work of Gibbs'sequations of state .*

Max Planck of Germany won the 1918Nobel prize in physics for his work inquantum mechanics , particularly his 1900 quantum theory paper. This work is largely based on the thermodynamics ofRudolf Clausius , Gibbs, andLudwig Boltzmann . Nevertheless, Planck said about Gibbs: "…whose name not only in America but in the whole world will ever be reckoned among the most renowned theoretical physicists of all times…".*At the turn of the 20th century,

Gilbert N. Lewis andMerle Randall used and extended Gibbs's work onchemical thermodynamics , published their results in the 1923 textbook "Thermodynamics and the Free Energy of Chemical Substances", one of the two founding books in chemical thermodynamics. In the 1910s,William Giauque entered the College of Chemistry at Berkeley, where he received a bachelor of science degree in chemistry, with honors, in 1920. At first he wanted to become achemical engineer , but soon developed an interest in chemical research under Lewis's influence. In 1934, Giauque became a full Professor of Chemistry at Berkeley. In 1949, he won theNobel Prize in Chemistry for his studies in the properties of matter at temperatures close to absolute zero, studies guided by thethird law of thermodynamics .* Gibbs strongly influenced the education of the economist

Irving Fisher , who was awarded a Yale Ph.D. in economics in 1896. One of Gibbs's protegés wasEdwin Bidwell Wilson , who in turn passed his Gibbsian knowledge to the Americaneconomist Paul Samuelson . In 1947, Samuelson published "Foundations of Economic Analysis ", based on hisHarvard University doctoral dissertation. Samuelson explicitly acknowledged the influence of the classical thermodynamic methods of Gibbs. [*Liossatos, Panagis, S. (2004). " [*] Samuelson was the sole recipient of the Nobel Prize in Economics in 1970, the second year of the Prize.

(reportedly spoken by Gibbs at a Yale faculty meeting)

*"A mathematician may say anything he pleases, but a physicist must be at least partially sane."

*"It has been said that 'the human mind has never invented a labor-saving machine equal to algebra.' If this be true, it is but natural and proper that an age like our own, characterized by the multiplication of labor-saving machinery, should be distinguished by the unexampled development of this most refined and most beautiful of machines."
