Noam Grossman was born on April 8, 1927 in Brooklyn, NY to Reuven (a poet) and to Chana. When Noam was two and a half years old, the family made aliyah and settled in Tel Aviv where he attended the Herzlia Gymnasium.
Noam joined the Haganah as a youth and during World War II he was drafted into the Jewish Brigade, but the war ended before he had a chance to join the unit.
Immediately after the November 29, 1947 UN resolution, he joined the Haganah fulltime and participated in many battles. On March 4, 1948 the unit he commanded - in response to Arab attacks on Jewish transport from Atarot and Neve Yaakov to Jerusalem - attacked an Arab bus on its way from Ramallah to Latrun. On the way back to their base the unit was surrounded by hundreds of Arabs near Atarot. Noam and 15 other soldiers were killed. They were buried three days later in Sanhedria and on September 6, 1951 their remains were transferred to Har Herzl. On March 17, 1985 the main street of the Pisgat Ze'ev neighborhood of Jerusalem was named in memory of the 16 members of the unit who were killed.
