Abstract

Roman Teisseyre was born on April 11, 1929, in Lwów (Lviv), to a family with French roots. In 1935, the family moved to Warsaw. After the outbreak of World War II on September 1, 1939, when the country fell under German occupation, Roman continues his school education in the underground classes. By the outbreak of the Warsaw Uprising (August 1, 1944), he managed to complete three grades of junior high school. At the age of 15, being a member of the underground scouting movement, the Polish Gray Scouts (Szare Szeregi), he participates in the uprising fights in the Żoliborz neighborhood, platoon 257 of the Group "Viper" ("Żmija", District II "Żywiciel" of the Home Army's Warsaw Region) taking the pseudonym "Grom". Roman's father Kazimierz and older brother Mieczysław, while fighting in the Uprising in the regions of Czerniaków and the Old Town, were wounded. After 63 days of the Uprising fights, Kazimierz and Mieczysław are sent to a prisoner-ofwar camp in Germany, while Roman and the civilian population go to the transit camp in Pruszków (Dulag 121). Eventually, the Teisseyres go to Jędrzejów and then to Cracow, already free from German occupation, where Roman, after completing the fourth grade of junior high school, obtains a minor high school diploma. The family then moves to Wrocław, upon shorter stays in the towns of Zielona Góra and Jelenia Góra. It should be noted that in these harsh times, young Roman tried to help the family by working in a mill near Cracow and as an industrial guard in Zielona Góra. He completes the first year of senior high school in Jelenia Góra and the second in Wrocław, getting the high school diploma in 1947. He begins studies at the Faculty of Mathematics, Physics, and Chemistry at the University of Wrocław.In the summer of 1948, he works as an observer in the Magnetic Group of Prof. Henryk Orkisz's team, doing magnetic measurements in the Kłodzko region on behalf of the State Geological Institute. After moving to Warsaw in 1949, he continues his physics studies at the University of Warsaw, also working at the Geophysics Department of the State Geological
