Jean Dumas, French chemist
Jean Dumas (1800-1884), French chemist. In 1830 Dumas challenged the views of Berzelius on chemical structure, proposing in its place his own type theory. This showed that there existed families of atoms or groups in organic compounds that could be substituted for each other without seriously altering the properties of the compound. Later, he devised an analytical method for the determination of nitrogen in organic compounds, a major step in quantitative organic analysis. In 1848 he entered politics, retiring in 1870.

EDITORS COMMENTS
This print showcases Jean Dumas, a prominent French chemist whose groundbreaking contributions revolutionized the field of chemistry in the 19th century. Known for challenging the established views of Berzelius on chemical structure, Dumas proposed his own type theory which revealed that organic compounds contained families of atoms or groups that could be substituted without significantly altering their properties. In addition to this remarkable discovery, Dumas devised an analytical method for determining nitrogen content in organic compounds, marking a significant milestone in quantitative organic analysis. His dedication and ingenuity propelled him to become one of the most influential figures in the history of science. Beyond his scientific achievements, this engraving also sheds light on another facet of Dumas' life. In 1848, he ventured into politics and continued serving until his retirement in 1870. This glimpse into his multifaceted persona adds depth to our understanding of this brilliant chemist. The monochrome illustration captures not only Dumas' likeness but also represents an era when scientific exploration was flourishing. The intricate details and artistic rendering make this artwork a testament to both historical significance and aesthetic appeal. As we admire this print from Science Photo Library, let us celebrate Jean Dumas as a visionary discoverer who expanded our knowledge of chemical structures and left an indelible mark on the world through his pioneering work in chemistry.
