While one is generally attributed to a fellow untryman, the other is well known as Gay-Lsac’s law.

Joseph Louis Gay-Lsac (1778–1850) grew up durg both the French and Chemil Revolutns.

Gay-Lsac’s own reer as a profsor of physics and chemistry began at the Éle Polytechnique. In 1804 Gay-Lsac ma several darg ascents of over 7, 000 meters above sea level hydrogen-filled balloons—a feat not equaled for another 50 years—that allowed him to vtigate other aspects of gas. In 1808 Gay-Lsac announced what was probably his sgle greatt achievement: om his own and others’ experiments he duced that gas at nstant temperature and prsure be simple numeril proportns by volume, and the rultg product or products—if gas—also bear a simple proportn by volume to the volum of the reactants.

Wh his fellow profsor at the Éle Polytechnique, Louis Jacqu Thénard, Gay-Lsac also participated early electrochemil rearch, vtigatg the elements disvered by s means. Joseph-Louis Gay-Lsac, (born December 6, 1778, Sat-Léonard--Noblat, France—died May 9, 1850, Paris), French chemist and physicist who pneered vtigatns to the behavur of gas, tablished new techniqu for analysis, and ma notable advanc applied chemistry. Gay-Lsac was the elst son of a provcial lawyer and royal official who lost his posn wh the French Revolutn of 1789.

Early his schoolg, Gay-Lsac acquired an tert science, and his mathematil abily enabled him to pass the entrance examatn for the newly found Éle Polytechnique, where stunts’ expens were paid by the state. The society’s first volume of memoirs, published 1807, clud ntributns om Gay-Lsac.

At Arcueil, Berthollet was joed by the ement mathematician Pierre-Simon Laplace, who engaged Gay-Lsac experiments on pillary orr to study short-range forc. Charl as “Charl’s law, ” was the first of several regulari the behavur of matter that Gay-Lsac tablished. ” Of the laws Gay-Lsac disvered, he remas bt known for his law of the bg volum of gas (1808).

Gay-Lsac’s approach to the study of matter was nsistently volumetric rather than gravimetric, ntrast to that of his English ntemporary John Dalton. Another example of Gay-Lsac’s fondns for volumetric rats appeared an 1810 vtigatn to the posn of vegetable substanc performed wh his iend Louis-Jacqu Thenard.

In a followg solo flight, Gay-Lsac reached 7, 016 metr (more than 23, 000 feet), thereby settg a rerd for the hight balloon flight that remaed unbroken for a half-century.

In 1805–06, amid the Napoleonic wars, Gay-Lsac embarked upon a European tour wh another Arcueil lleague, the Pssian explorer Alexanr von Humboldt.

HOW GAY CULTURE BLOSSOMED DURG THE ROARG TWENTI

Gay-Lsac’s rearch together wh the patronage of Berthollet and the Arcueil group helped him to ga membership the prtig First Class of the Natnal Instute (later the Amy of Scienc) at an early stage his reer (1806). Three years prevly Gay-Lsac had been appoted to the junr post of répétr at the Éle Polytechnique where, 1810, he received a profsorship chemistry that clud a substantial salary. Gay-Lsac’s appotment to the faculty of the Éle Polytechnique 1804 provid him wh laboratory facili the centre of Paris.

Rivalry between Gay-Lsac and Davy reached a climax over the de experiments Davy rried out durg an extraordary vis to Paris November 1813, at a time when France was at war wh Bra. Gay-Lsac prented a much more plete study of de a long memoir prented to the Natnal Instute on Augt 1, 1814, and subsequently published the Annal chimie. In 1815 Gay-Lsac experimentally monstrated that pssic acid was simply hydrocyanic acid, a pound of rbon, hydrogen, and nrogen, and he also isolated the pound cyanogen [(CN)2 or C2N2].

Begng 1816, Gay-Lsac served as the jot edor of the Annal chimie et physique, a posn he shared wh his former Arcueil lleague François Arago.

Still, Gay-Lsac did not pe cricism om lleagu for turng away om the path of “pure” science and toward the path of fancial ga. Gay-Lsac was a key figure the velopment of the new science of volumetric analysis. Prevly a few c trials had been rried out to timate the strength of chlore solutns bleachg, but Gay-Lsac troduced a scientific rigour to chemil quantifitn and vised important modifitns to apparat.

The prcipl of volumetric analysis uld be tablished only through Gay-Lsac’s theoretil and practil geni but, once tablished, the analysis self uld be rried out by a junr assistant wh brief trag. Gay-Lsac published an entire seri of Instctns on subjects rangg om the timatn of potash (1818) to the nstctn of lightng nductors.

In 1831 Gay-Lsac was elected to the Chamber of Deputi and 1839 received a peerage. In 1848 (the year of revolutns) Gay-Lsac rigned om his var appotments Paris, and he retired to a untry hoe the neighbourhood of his youth that was stocked wh his library and a private laboratory. ” In a logy livered after his ath at the Amy of Scienc, his iend, the physicist Arago, summed up Gay-Lsac’s scientific work as that of “an gen physicist and an outstandg chemist.

By the mid-1920s, at the height of the Prohibn era, they were attractg as many as 7, 000 people of var rac and social class—gay, lbian, bisexual, transgenr and straight alike. Stonewall (1969) is often nsired the begng of forward progrs the gay rights movement.

” This not only disuraged gay men om participatg public life, but also “ma homosexualy seem more dangero to the average Amerin. ” By the post-World War II era, a larger cultural shift toward earlier marriage and suburban livg, the advent of TV and the anti-homosexualy csas champned by Joseph McCarthy would help ph the flowerg of gay culture reprented by the Pansy Craze firmly to the natn’s rear-view mirror. In Berl there were a large number of openly homosexual, transvte and lbian bars where people met and socialised.
