Bruno Abdank-Abakanowicz (6 October 1852 – 29 August 1900) was a Polish mathematician, inventor and electrical engineer.
Bruno completed his education and after that started to think about his own career. As mentioned above, he joined Technical university of Lwow for his assistantship in the year of 1881 and that was his first ever practical work experience of the field. Later on, he migrated to France and tried to buy a villa. He got succeeded in that and hence as a result, he purchased that in the Paris which was located in Parc St. Maur. He is always considered as a scientist.
Earlier he invented the integraph, a form of the integrator, which was patented in 1880,and was henceforth produced by the Swiss firm Coradi.Among his other patents were the parabolagraph, the spirograph, the electric bell used in trains, and an electric arc lamp of his own design.Abakanowicz published several works, including works on statistics, integrators and numerous popular scientific works, such as one describing his integraph. He was also hired by the French government as an expert on electrification and was the main engineer behind the electrification of, among other places, the city of Lyon.His patents allowed him to become a wealthy man and made him receive the Legion d'Honneur in 1889.
Around that time he retired to a small island in Trégastel, off the coast of Brittany, where between 1892 and 1896 he erected a neo-Gothic manor.Although the construction works were not finished in Abakanowicz's lifetime, the castle of Costaérès became a notable centre of Polish emigree culture, housing many notable artists, scientists and politicians. Among frequent guests of Abakanowicz were Aleksander Gierymski, W?adys?aw Mickiewicz, Leon Wyczó?kowski and Henryk Sienkiewicz. The latter became the closest friend of Abakanowicz. It was in Abakanowicz's villa in Parc St. Maur that he finished his The Teutonic Knights and The Polaniecki Family, while the Quo Vadis novel, one of the works for which Sienkiewicz was awarded with the Nobel Prize, was written entirely in Abakanowicz's manor.
Bruno Abakanowicz died suddenly on 29 August 1900. In his will, he made Sienkiewicz the tutor of his sole daughter Zofia, who later graduated from the London School of Economics and the Sorbonne and was murdered during World War II at the Auschwitz concentration camp.
