Lapid Mordekhai (Mordechai) (Blum Mark) (1937, Kharkiv – 1993, Hebron, Israel), public figure.

After 1945, Mordekhai Lapid settled with his family in Riga. He studied at the Riga Polytechnic Institute and graduated from the mechanical engineering department of the Latvian Agricultural Academy. In the 1960s, he was an activist in the Jewish revival movement in Riga. He was one of the initiators and active participants in the creation of a memorial at the site of the mass shootings of Jews in Rumbula (near Riga). In 1966, he was arrested and sentenced to two years in prison on charges of assaulting a police officer and organising riots after a concert by Israeli singer Geula Gil in Riga. He was released under an amnesty in 1967. From 1968, he lived in Israel. He worked as an engineer and studied in yeshivas. In 1973, he became an active participant in the Gush Emunim settlement movement. In 1975, he wrote and published a pamphlet proposing the creation of a city in Samaria for immigrants from the USSR. In the 1990s, he studied at a Kabbalist yeshiva in Hebron. At the same time, he completed an unpublished work in which he presented an original concept of Jewish and world history in the light of the theory of evolution, consistently combining the principles of modern genetics with traditional Kabbalistic ideas. He was killed together with his son Shalom by Hamas terrorists.
