Childhood and youth Isser Harel was born as Yisrael Natanovich Halperin in 1911 in the city of
Vitebsk, within the
Pale of Settlement of the
Russian Empire (modern-day
Belarus), as the fourth child to a wealthy Jewish family. His father, Rabbi Natan-Neta Halperin, was a graduate of the Lithuanian
Volozhin Yeshiva, and his mother, Yocheved (née Levin), was a homemaker, the daughter of a wealthy local Jewish industrialist. His exact birthdate is unknown; it was recorded in his father's
Talmud volume, but the book was lost due to the upheavals of the
Russian Revolution and
World War I. The Halperin family owned a
vinegar factory in Vitebsk, a gift from his maternal grandfather, who had held a
concession to produce vinegar in large parts of
Tsarist Russia. Whilst six years old, the
Russian Civil War broke out, and Vitebsk changed hands several times between the
Whites and the
Reds. He once attended a speech given by
Leon Trotsky in his city. The
Soviet regime confiscated the family's property, and they suffered from hunger. In 1922, the family left the
Soviet Union and relocated to the city of
Daugavpils in independent
Latvia. On their way, Soviet soldiers robbed them of their remaining possessions. In Daugavpils, he received a formal education, completing elementary school and beginning high school studies. In his book
Security and Democracy, he describes a significant event in the city related to Rabbi
Meir Simcha of Dvinsk, who served as the local rabbi. He writes that during a particularly rainy winter, the local river overflowed, threatening to breach the dam and flood the city. Rabbi Meir Simcha prayed for mercy, and shortly afterward, the waters began to recede, saving the city. As he grew older, his Jewish national consciousness awakened, and he joined a
Zionist youth movement. At the age of 16, Yisrael left for
hachshara (agricultural training) in preparation for
aliyah to
Mandatory Palestine. During his year of training, he worked in
agriculture, aspiring to join a
kibbutz. In 1929, following the outbreak of the
1929 Arab riots, his group decided to expedite their immigration to Palestine to support the
Yishuv. At 17, Yisrael obtained forged documents that claimed he was 18, which allowed him to receive a certificate of immigration (certificat) from the
British Mandate. In early 1930, he made
aliyah, crossing
Europe from north to south and boarding a ship in
Genoa bound for Palestine. He carried a
pistol, which he concealed in a loaf of bread.
In Mandatory Palestine In Palestine, Yisrael joined the group from
HaKibbutz HaMeuhad that founded Kibbutz
Shfayim. Initially, he worked as a pioneer in the
citrus orchards of the
Sharon plain and in a packing house. During this time, he married Rivka, his kibbutz companion. In 1935, Yisrael and his wife decided to bring their families to Palestine. Yisrael took out loans to finance their immigration, and both families came to live with them in the kibbutz. He asked the kibbutz for help repaying the loans, but his request was denied. As a result, the three families left the kibbutz and moved to
Herzliya. They lived communally in a dilapidated hut, earning their livelihood as packing house workers. Eventually, Yisrael began working as a contractor installing irrigation pipes in orchards, and the family emerged from their financial difficulties. Yisrael and Rivka had one daughter.
Intelligence in the Pre-State Era With the outbreak of
World War II, Yisrael felt he could not continue his profitable work while his friends enlisted in the
British Army or the
Palmach. In 1942, he approached the
Haganah in Herzliya and volunteered. This was during the period when
Erwin Rommel's German forces were advancing toward Palestine (a period known as the "200 Days of Dread"). The Haganah decided that priority should be given to the defense of the land and sent Yisrael to a Haganah commander's course. Upon returning from the course, he was assigned to the coastal guard in British uniforms, but his main activity was within the Haganah's intelligence service, the
Shai. Yisrael was reassigned from the coastal guard after he assaulted a corrupt British officer who made
antisemitic remarks. He was placed in the
Jewish Settlement Police (the Notrim) while continuing his role in the Shai. In 1944, Yisrael was summoned by
Israel Amir (Zabludovsky), the commander of the Shai, who informed him that he was being assigned to serve in the Shai headquarters in
Tel Aviv. This marked the beginning of his long career in commanding positions within the intelligence services of the pre-state Yishuv and later the intelligence community of Israel. Yisrael began working at the Shai headquarters in Tel Aviv at the end of 1944, serving as the secretary of the "Jewish Department." The department was headed by Yosef Karo, and Yisrael served as his assistant. The department's role was internal security, and it dealt, among other things, with gathering intelligence on underground movements that did not accept the authority of the national institutions, such as the
Irgun and
Lehi, as well as on the activities of
communists. A few months after starting as the department's secretary, Yisrael was appointed to head the department. In 1947, Yisrael's name came to the attention of
David Ben-Gurion. He was introduced to Ben-Gurion and reported on the activities of his department. During that meeting, Ben-Gurion decided to rename the "Jewish Department" to the "Internal Department." Yisrael succeeded in his role and became an unofficial spokesman for the Shai. He maintained fair relations with members of other underground movements, who were under his department's surveillance. At the Shai headquarters, Yisrael earned the nickname "Isser the Small," both due to his short stature and to distinguish him from "Isser the Great,"
Isser Be'eri (Birenzweig), who joined the Shai headquarters in 1947 and was tall in stature. Be'eri later became the head of Israeli Military Intelligence, but was dismissed following the Ali Qassem Abed al-Qader affair. In 1947, Yisrael was appointed the commander of the Tel Aviv District of the Shai, responsible for gathering intelligence from Arab
Jaffa. This was a challenging period for the Shai, following Black Saturday and due to the decline in the number of Arab informants, a result of the national awakening among Jaffa's Arabs leading up to the
War of Independence. Yisrael took steps to recruit new sources and succeeded in doing so. Shortly before the declaration of the State of Israel, Yisrael deployed an Arab agent on a mission to
Amman to assess Jordan's intentions and whether they planned to go to war. The agent reported that the Jordanians intended to join the war, and Yisrael hurried to inform Ben-Gurion.
Intelligence in the State of Israel Upon the establishment of the State of Israel, Yisrael was given the rank of
Lieutenant Colonel, then one of the highest ranks, just below
Colonel (the rank of Aluf-Mishneh was only added in 1950, and the rank of
Tat Aluf was introduced only after the
Six-Day War). He was appointed to head the "Shin Bet" (General Security Service), a branch of the
IDF. (Later, the service became an independent organization outside the IDF framework, also known as the
Shin Bet). The service under Yisrael's leadership had to be built from scratch, determining its principles, organizational structure, and methods of operation. One of the basic principles he established was that the employees of the organization had to be full-fledged government employees, with appropriate ranking, salary, and social benefits, without the special privileges and perks typically associated with secret service personnel in undemocratic countries. Another principle set by Yisrael was that employees had to maintain a high moral standard, with no criminal background and no adventurist tendencies. This principle, he claimed, was not adopted by military intelligence at that time, leading to scandals such as the Avri Elad and Mordechai Kedar cases. Yisrael also decided to break down the political and party-based barriers that existed before the establishment of the state. He employed, without distinction, former members of the Haganah, Palmach, Irgun, and Lehi in the Shin Bet and later in the
Mossad. This inclusive approach allowed individuals such as
Yitzhak Shamir, a former commander of the Lehi and later
Prime Minister of Israel, to be integrated into Israel's intelligence services. This policy contrasted with the prevailing sentiment of the time, expressed by
David Ben-Gurion in his policy of "Without Herut and Maki", which marginalized members of the political right. Employing right-wing figures in government institutions was not common practice. During the
1948 Arab–Israeli War, the Shin Bet was primarily engaged in internal security matters. After the war, the service expanded its operations to include
counter-espionage and the monitoring of
Israeli Arabs for intelligence purposes.
Involvement with Ben-Gurion and political surveillance At this time, Yisrael grew closer to Prime Minister and Minister of Defense
David Ben-Gurion. Much of the information he provided Ben-Gurion around 1951 pertained to subversive activities against the state. However, in addition to providing intelligence of national importance, Yisrael also supplied politically charged information, including recommendations for actions by
Mapai (Ben-Gurion's party) and details of developments within opposition parties. In 1951, the
Mossad for Intelligence and Special Operations was established, with
Reuven Shiloah as its head. In September 1952, Shiloah resigned and suggested to David Ben-Gurion that Yisrael Halperin (now known as Isser Harel) replace him. == Head of the Mossad ==
