 in 1831. They married on 3 November 1866.

On 9 April 1867, the first male child of the Tissot couple was born, but died suddenly two years later. Camille Papin Tissot was their second child, born on 15 October 1868. Their third child, Esther Adèle Tissot, was born on April 1, 1872. The two surviving children, Camille and Esther, were primarily raised by their mother, as their father was often at sea.

Naval career

Recommended by his father, Camille Tissot entered the naval college at Brest in 1884 when he was 16 years old.
He learned navigation on the school ship Le Borda

In the first years of his career in the navy, he was successively posted to various school ships and warships, finally on the cruiser "Coetlogon". He then turned to shore duty as of January 23, 1891. He agreed to temporarily occupy one of the teaching positions in physics

  • October 5, 1889: Enseigne de vaisseau,
  • August 22, 1896: Lieutenant de vaisseau,
  • April 19, 1912: Capitaine de frégate,

This last promotion is exceptional for a sailor who practically never sailed, and it was due to the importance of the work undertaken by Tissot for the Navy.

Marriage

In 1894 Camille Tissot met and married Jeanne Emma Stapfer, a 20 year old woman of an Alsacienne family who moved to Brest in 1870. He nominally converted to the Catholic religion at the request of his father-in-law, although his own beliefs were socialist and atheist. Among the guests at his wedding were Albert Turpain and Marcel Cachin

  • The August 3, 1898, in the presence of the Minister for the Navy, it establishes the first radio connection operational French at sea: 800 meters between "BORDERED" and the semaphore of the Park to the Dukes with Brest. Convinced, the Minister prescribes on August 6 with the wearing of Brest, to finance in Tissot the purchase of material to allow him to continue his tests.

  • With these apparatuses, Camille Tissot goes up in 1899 a large trial run and ensures of the communications by Hertzian waves, initially between various points of the roads of Brest and the church Saint Martin, then to the island Vierge (Plouguerneau

  • From 1905, Tissot makes very thorough studies on the detection of the radio operator signals. The files of Tissot and its books of experiments let think that it is that which pushed further the tests in this field in France.

  • In 1907, Tissot conceives, with F Pellin, one receptor with crystal without tiresome adjustment to receive these signals aboard tradind ships.

  • In 1911, its technical expertise is required by a committee of French industrialists carried out by E Girardeau, during the series of lawsuits which oppose Marconi and the French industry of the radioelectric TSF:la French company and the radioelectric general company. With the occasion of these lawsuits, Tissot and Férrié will in particular seek to show certain faults of patent 77777 of Marconi, but also the anteriority of experiments of certain French scientists, like Eugene Ducretet. Marconi gains the lawsuit in first authority against the sfr and the cgr, but this decision of court which gave the right to marconi to require the replacement of the French material by material of the wireless company, will never be applied in France. Since in 1914, Marconi sees itself débouté definitively of his request.

Today in 1909 all the warships provided with the devices studied by Mr. Tissot can communicate to 300 km. In 1906, the battleship "Bruix" could even communicate with Port Vendres, at a distance of 500 km. Albert Turpain.

Work

He wrote three detailed works: Mémoire de thèse de Doctorat sur la résonance des antennes (1905). Memory of thesis of Doctorate on the resonance of the antennas. Traité sur les oscillations électriques (1906) Treaty on the electric oscillations. Manuel de TSF théorique et pratique (1912), Handbook of theoretical and practical TSF (1912), republished until 1932 (6th edition). books written by Camille Tissot.

He is also the author of many articles of popularization of radio in international scientific reviews, and will give very many conferences on the subject. Although not a member, he intervenes regularly in front of the Academy of the sciences . He received several prizes and rewards of the Academy.
