Adam was born in 1902 in the village of Berezowica Mała (near Zbaraz, now in Ternopil Oblast, Ukraine) to Franciszek Lazarowicz and Wanda, née Ojak.

Due to an unknown sickness, Lazarowicz was dismissed from the Army and took up the job of a teacher in a school in the village of Gumniska, a few kilometers from Dębica.

In 1940 Lazarowicz became engaged in the anti-German Sluzba Zwyciestwu Polsce organization, then joined the Zwiazek Walki Zbrojnej.

Later, he was promoted to commander of Dębica (“Deser”) District of the Home Army (Armia Krajowa) and remained on this post until spring of 1944.

However, he refused to accept it and in February 1945 moved to Rzeszów, where he became commander of the Rzeszow District of Wolnosc i Niezawislosc, an anti-communist Polish underground organization.

For fifty years, Lazarowicz's story was censored from all publications by the Soviet-imposed Communist government of the People's Republic of Poland.

In 1992, after the collapse of the Communist system, the Military Court of the Warsaw District issued a decree which voided the 1951 sentence.
