Early Life and Education

Gabriel-Augustin Lamé was born in Tours, France, on July 17, 1795, to Gabriel-François Lamé and Julie Goualard La Drouais. During the French Revolution, the Lamés' fortunes dwindled, forcing them to relocate to Paris. From 1810 to 1814, young Lamé attended the prestigious Lycée Louis le Grand.

Upon graduating from the lycée, Lamé enrolled in the École Polytechnique, graduating in 1817. He subsequently pursued advanced studies at the École des Mines.

Service in Russia

In 1820, Lamé and Émile Clapeyron were invited to Russia to teach at the Institute of Engineers in St. Petersburg. While remaining on assignment from the French mining corps, Lamé joined the Russian Corps of Engineers on July 13, 1820. He rapidly rose through the ranks, attaining the rank of colonel in 1829.

During his tenure in Russia, Lamé held the first professorship in applied mechanics in Russia at the Institute of Engineers. He also conducted scientific research, designing bridges and structures, and served on construction committees and commissions. In 1830, he traveled to England to study British transportation systems and met the renowned engineer George Stephenson.

Marriage and Family

In October 1823, Lamé married Marie Marguerite Féortune Bertin de Gérando, a Frenchwoman. They had two sons and a daughter.

Recognition and Honors

Lamé was highly decorated during his service in Russia, receiving the Order of St. Vladimir, Order of St. Anne, and Order of St. Stanislaus. In 1831, he was awarded the Legion of Honor, but did not receive permission to wear it on his Russian uniform.

Return to France

With the deterioration of Franco-Russian relations following the July Revolution, Lamé resigned from his Russian post in 1831 and returned to France. He was appointed Professor of Physics at the École Polytechnique in 1832 and became involved in railroad construction.

Later Career and Achievements

Lamé was elected to the French Academy of Sciences in 1843 and joined several other scientific societies. He held the chair of probability theory at the University of Paris from 1848, teaching courses on the mathematical theory of elasticity, heat, and elliptical functions. Despite his severe hearing loss, Lamé continued to work until his retirement in 1863.

Legacy

Gabriel-Augustin Lamé made significant contributions to mathematical physics and elasticity theory. He developed the general theory of curvilinear coordinates, introduced Lamé coefficients, and defined a special class of functions known as Lamé functions. He also played a pivotal role in railroad construction and is remembered today for his parameters in elasticity theory.
