Josiah Willard Gibbs From Wikipedia, the free encyclopedia

Josiah Willard Gibbs (February 11, 1839 – April 28, 1903) was an American J. Willard Gibbs theoretical , chemist, and mathematician. He devised much of the theoretical foundation for chemical as well as physical . As a mathematician, he invented (independently of ). awarded Gibbs the first American Ph.D. in in 1863, and he spent his entire career at Yale.[1]

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 of the Royal Society of London, for his greatest contribution of being "the first to apply the second law of thermodynamics to the Josiah Willard Gibbs exhaustive discussion of the relation Born between chemical, electrical, and February 11, 1839 thermal and capacity for external New Haven, ."[2] Died April 28, 1903 (aged 64) New Haven, Connecticut Residence United States Contents Nationality United States Fields and chemistry ■ 1 Biography Institutions Yale University ■ 1.1 Early years ■ 1.2 Middle years Alma mater Yale University ■ 1.3 Later years Doctoral advisor ■ 2 Scientific recognition Doctoral students ■ 3 Influential work ■ 4 Commemoration Henry Andrews Bumstead ■ 5See also ■ 6Notes Known for Father of ■ 7 References ■ 8 External links Gibbs Vector analysis Gibbs-Helmholtz equation Biography Gibbs-Duhem equation Gibbs algorithm Early years Gibbs distribution

Gibbs was the seventh in a long line of American academics stretching back to Gibbs' the 17th century. His father, a professor Gibbs-Thomson effect of sacred literature at the Yale Divinity Gibbs isotherm School, is now most remembered for his Gibbs-Donnan effect involvement in the Amistad trial. The Gibbs lemma Although the father was also named Influences Josiah Willard, the son is never referred to as "Jr." Five other members of Gibbs's extended family were named Josiah Notable awards (1880) Willard Gibbs. His mother was the Copley Medal (1901) daughter of a Yale graduate in literature. Signature

After attending the , Gibbs matriculated at at Notes the age of 15. He graduated in 1858 near He is the son of theologian Josiah Willard Gibbs, Sr. the top of his class, and was awarded prizes in and Latin.

Middle years

In 1863, Gibbs was awarded the first Ph.D. degree in engineering in the USA from the Sheffield Scientific School at Yale for a thesis entitled On the Form of the Teeth of Wheels in Spur Gearing. He then tutored at Gibbs in his youth. Yale, two years in Latin and one year in what was then called natural Founder of chemical philosophy, now comparable to the natural sciences, particularly thermodynamics. physics. In 1866 he went to Europe, along with his two elder sisters, to study, spending a year each at Paris, , and , where he was influenced by Kirchhoff and Helmholtz. At the , German academics were the leading authorities in chemistry, 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 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 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 of physical chemistry. In these papers Gibbs applied thermodynamics to interpret physicochemical phenomena, successfully explaining and interrelating what had previously been a of isolated facts.

"It is universally recognised that its publication was an event of the first importance in the . ... 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 of experimental chemistry whom it most concerns... " (J J O'Connor and E F Robertson, J. Willard Gibbs (http://www.shsu.edu/~icc_cmf/bio/gibbs.html) )

Some important topics covered in his other papers on heterogeneous equilibria include:

■ The concepts of and free energy (available energy); ■ A Gibbsian ensemble ideal, a foundation of statistical ; ■ The Gibbs phase rule.

Gibbs also wrote on theoretical thermodynamics. 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 in , offered Gibbs a position paying $3000. Yale responded by raising his salary to $2000, and he did not leave New Haven. From 1880 to Willard Gibbs’ 1873 1884, Gibbs combined the ideas of two mathematicians, the of and the exterior of available energy (free to obtain vector analysis (independently energy) graph, which shows formulated by the British mathematical physicist and engineer a plane perpendicular to the Oliver Heaviside).

Scientific 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 and chemists, such as the Scot , paid any attention to his work. Only when Gibbs's papers were translated into German (then the leading language for chemistry) by in 1892, and into French by Henri 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, the American Academy of Arts and Sciences awarded Gibbs its Rumford Prize for his work in .[5] ■ In 1910, the American established the Willard Gibbs Medal in his memory, through William A. Converse (1862–1940), a former chairman/secretary of the Section.[6]

During 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 of Sterling 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, and Mach. 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 and Merle 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 for chemical engineering.

According to the American Mathematical Society, which established the Josiah Willard Gibbs Lectureship in 1923 to increase public awareness of the aspects of mathematics and its applications, Gibbs is one of the greatest scientists America has ever produced.[7]

In 1945, Yale University created the J. Willard Gibbs Professorship in Theoretical Chemistry, held until 1973 by , 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.[8]

Rutgers University has a J. Willard Gibbs Professorship of Thermomechanics (http://www.mechanics.rutgers.edu/Vita.pdf) presently held by Bernard D. Coleman.[9]

In 1950, Gibbs was elected to the Hall of Fame for Great Americans.

On May 4, 2005, the United States Postal Service issued the American Scientists commemorative postage stamp series, depicting Gibbs, , Barbara McClintock and . Influential work

The work of Gibbs attracted much attention, and influenced a number of scientists, some of whom became Nobel laureates:

■ Johan van der Waals of the Netherlands won the 1910 . In his Nobel Lecture, he acknowledged the influence on his work of Gibbs's equations of state. ■ of Germany won the 1918 Nobel prize in physics for his work in quantum mechanics, particularly his 1900 quantum theory paper. This work is largely based on the thermodynamics of , Gibbs, and . 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 ."[10] ■ At the turn of the 20th century, Gilbert N. Lewis and Merle Randall used and extended Gibbs's work on chemical 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 of science degree in chemistry, with honors, in 1920. At first he wanted to become a chemical 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 the Nobel Prize in Chemistry for his studies in the properties of matter at close to absolute zero, studies guided by the third law of thermodynamics. ■ Gibbs strongly influenced the education of the economist Irving Fisher, who was awarded the first Yale Ph.D. in economics in 1891.[11] One of Gibbs's protegés was Edwin Bidwell Wilson, who in turn passed his Gibbsian knowledge to the American economist .[12] In 1947, Samuelson published Foundations of Economic Analysis, based on his Harvard University doctoral dissertation. Samuelson explicitly acknowledged the influence of the classical thermodynamic methods of Gibbs.[13] Samuelson was the sole recipient of the Nobel Prize in Economics in 1970, the second year of the Prize.[14] In 2003, Samuelson described Gibbs as "Yale's great physicist".[12] ■ cited Gibbs as a major influence on his conception of . "This book is devoted to the impact of the Gibbsian point of view on modern life, both through the substantive changes it has made to working science, and through the changes it has made indirectly in our attitude to life in general"[15]
