Shulamit was born on 19.4.1923 in Sofia, Bulgaria, as Sarikah Levi to Hannah and Eliyahu. The family was Sephardic and traditional, and the shadow of her grandfather dominated the family, as he was well-off and well-liked. From her grandfather she absorbed, at a young age, the values of Judaism and a yearning for the Land of Israel. Her father, on the other hand, was an army officer, pharmacist and accountant, uninterested in Zionism and opposed to aliyah. Shulamit was educated in a Jewish school and then in a general Bulgarian high school. In her youth, she joined Beitar, and she was active until she made aliyah.

In 1941, as a senior in high school, Shulamit decided that the time had come to make aliyah, so she abandoned her studies and made aliyah illegally with a Beitar group. After a long and exhausting trip in a rickety ship, along with harsh storms and a risk of drowning, she reached the Land of Israel in 1941. The boat was seized by the British and its passengers were sent to Mizra.

This was when she first made connections with Lehi. Once she was released, she joined the movement and became an active operative, and she picked the nom de guerre Shulamit, which eventually became her legal name. She supported herself with odd jobs.

When Yitzhak Shamir fled in late 1942 from Mizra and rearranged Lehi, he put Shulamit in charge of his communications. Her rented room was a hiding place for Shamir and Lehi leaders. Shulamit became the permanent escort of the head of Lehi, and in 1944, they married, while still serving in the underground. In 1945, their firstborn Yair was born. After Yitzhak was arrested in 1946, she continued her activities, leading to her arrest by the CID in 1947. For eleven days, she maintained a hunger strike, and only Rabbi Aryeh Levin, the prisoners’ rabbi, convinced her to stop. She was finally released on 1.5.1948.

Once the State of Israel was established, Shulamit accompanied her husband throughout his career, in the Mossad and in the Knesset, as he went from Speaker to Foreign Minister to Prime Minister of Israel. As the wife of a high political official, she was a hostess for dignitaries and accompanied him to all sorts of government functions. She carried out her duties to a T; but above all, she was a dedicated, loyal friend and partner to her husband, providing him love and a warm home in which he could relax from the stress and exhaustion of his position.

Beyond her official functions, she also dedicated time to helping those in need and speaking to and for them. She established a non-profit for seniors and served as its president, and she also served in many other institutions for public and social welfare. Shulamit went back to Bulgaria a number of times to visit, and she was greeted with enthusiasm. She helped considerably in the warming of relations between the two countries. In 1991, the government of Bulgaria honored her with a commendation for activities in this area.

Shulamit and Yitzhak Shamir had two children: Yair, a colonel in the Air Force, and Gilada.
