In a short time, Segre was involved in various business activities. He took over shares of companies like Jutificio di Trieste and Pastificio Triestino and increased his business empire by owning a modern pasta factory in Dalmatia, another in Milan, an amideria in Danzig (now Gdansk, Poland), a chain factory in Lecco, and the Weissenfels Steelworks complex in Fusine. Segre became the president of various organizations, including the Stock Exchange Management, Officine Navali Triestine, Ampelea, Carbo-Arsa, and the Italian-Hungarian Chamber of Commerce. Despite being a Jew, Segre was a convinced fascist and a close associate of Benito Mussolini, who trusted him with important tasks. As President of the limited coal company Carbo-Arsa, Segre set up Carbosarda in 1933 and was appointed President of A.Ca.I. in 1935, a state company that managed coal basins in Italy. Segre organized the coal mines of the Sulcis mining basin and built Carbonia and two satellite mining villages, Bacu Abis and Cortoghiana. 
After the introduction of the Racial Laws in 1938, Segre was dismissed from all his positions. His past contributions to Italy and the Fascist regime were disregarded and his friendship with prominent public figures could not help him from escaping persecution. He died in Rome, were he hid with fake papers.

Guido Segre (1871-1954), admiral of the Italian Navy, born in Modena, Italy. In 1886, Segre entered the Naval Academy in Livorno, starting his career in the Italian Navy. He began as a midshipman and served on various ships including the Euridice, Ancona, and Lombardia. Segre's commitment to service and dedication to his duties led to his appointment as commander of the battleship Dandolo from 1899 to 1900. He continued to climb the ranks, occupying various positions where he focused on handling weapon-related issues, particularly artillery. During WWI, Segre commanded his own ship, and in 1917, he was promoted to captain of the 1st rank (capitano di vascello). His expertise and skills were highly valued, leading him to become the head of the Naval Armaments Corps of the Italian Navy.

In 1923, Segre was promoted to the rank of rear admiral (contrammiraglio). Three years later, he was promoted to vice admiral (ammiraglio di divisione), a testament to his leadership and exceptional service in the Navy. He rose through the ranks, becoming an admiral (ammiraglio di squadra) in 1932.

Annetta Segre (1897-1944), mathematician, born in Vercelli, Italy. After graduating from the Technical Institute of Asti in 1914, she enrolled in the mathematics program at the University of Torino. During her studies, she had the opportunity to learn from notable mathematicians such as Enrico d'Ovidio, Giuseppe Peano, and Corrado Segre, who taught algebraic geometry. She developed a strong interest in applied mathematics, including mathematical physics, theoretical geodesy, and experimental physics. After graduating, she trained to become a teacher and served in a special laboratory for students during WW I, making clothes and blankets for soldiers and refugees. Segre belonged to a group of about twenty Jewish mathematics teachers who followed Corrado Segre's lessons. Until the introduction of racial laws in 1938, Segre was well integrated into the Italian scientific community, participating in conferences and attending meetings of the Italian Mathematical Union and the Italian Society for the Progress of Sciences.

However, with the advent of the racial laws, Segre was expelled from these organizations, and her teaching position was terminated. She was arrested in 1943 and transferred to prisons in Milan before being deported to Auschwitz in January 1944. She arrived at the Nazi death camp on February 6, 1944, and did not survive the Holocaust. Although she did not publish any works, Segre made significant contributions to the field of mathematics, and her legacy has been recognized in recent years with various tributes and honors.

Claudio Segrè (1853-1928), mathematician and engineer, born in Bozzolo in the Perovince of Mantova, Italy. He studied at the University of Pavia, where he obtained a diploma in mathematics in 1874. He enrolled in the first year of the section for engineers of the Royal School of Application of Torino and obtained a degree in Atmospheric Gas Engines and then followed a specialization course in geological and mineralogical sciences at the École des Mines in Paris, where he learned about the scientific methodology of construction works. After returning to Italy, Segrè began his career as an engineer in the railway sector. In 1881, he started working for the Italian Company for Southern Railways, where he was in charge of designing and constructing new railway routes in southern Italy. In 1885, he established the Adriatic Company and supervised the works in the city of Ancona for 20 years. He believed that the railway network needed a scientific approach for choosing routes and conducting works. The geomorphological conditions of Italy, particularly the Apennine ridge, posed difficulties in building numerous crossings. Segrè evaluated which soils were reliable in terms of stability and which were the most suitable building materials in terms of quality and resistance. Segrè set up a research facility in Naples, and later in Ancona, where he created a real laboratory for the study of building materials to improve the operation of existing railway lines. When the Italian State resumed direct management of the railway network in 1905, Segrè worked alongside Riccardo Bianchi, the first director of the newly created State Railways. Segrè's scientific methodology played a significant role in the development of the Italian railway network. He died in Rome.

Liliana Segre (b.1930), Holocaust survivor and anti-fascist activist, Italian senator, born in Milan, Italy. In 1938, and was forced to leave elementary school due to the fascist racial laws. In 1943, she attempted to flee to Switzerland with her father but was rejected. She was arrested in Selvetta di Viggiù and transferred to several prisons, including Varese, Como, and Milan. In 1944, she was deported to Auschwitz-Birkenau Nazi death camp with her father and paternal grandparents that all died. Segre was tattooed with the number 75190 and forced to work in the Union munitions factory. She was liberated by the Red Army in 1945 and is one of the only twenty-five Italian-born children under the age of fourteen to have survived Auschwitz.
