The year 1875 in science and technology involved some significant events, listed below.

Chemistry

Gallium is discovered spectroscopically by French chemist Paul Emile Lecoq de Boisbaudran. Later in this year he obtains the free metal by electrolysis of its hydroxide and names it. This is the first of Dmitri Mendeleev's predicted elements to be identified.^[1]^[2]^[3]
Phenylhydrazine is discovered by Hermann Emil Fischer.^[4]
Swiss chocolatier Daniel Peter working with Henri Nestlé's company perfects a method of manufacturing milk chocolate using condensed milk.^[5]

Earth sciences

March – Challenger expedition first records Challenger Deep.

Genetics

Francis Galton publishes The History of Twins, as a criterion of the relative powers of nature and nurture.^[6]

Medicine

March 1 – The Hospital for Sick Children (Toronto) is founded in Canada.
The weekly medical journal, Deutsche Medizinische Wochenschrift , is established in Germany by Paul Börner.^[7]

Metrology

May 20 – International Bureau of Weights and Measures established by signature of the Metre Convention in Paris.

Paul-Émile Lecoq de Boisbaudran, also called François Lecoq de Boisbaudran, was a French chemist known for his discoveries of the chemical elements gallium, samarium and dysprosium. He developed methods for separation and purification of the rare earth elements and was one of the pioneers of the science of spectroscopy.

<i>Deutsche Medizinische Wochenschrift</i> Academic journal

The Deutsche Medizinische Wochenschrift (DMW) is a German medical journal established in 1875 by Paul Albrecht Börner. In the 1980s it was ranked 10th in the world in terms of its impact factor, but in the succeeding two decades the journal lost much of its preeminence due largely to the declining importance of the German language in medical publications and the appearance of a large number of new medical journals in the English language.
