SAN ANTONIO - Jaime Martinez was Chairman of the Cesar E. Chavez Legacy and Educational Foundation. He was instrumental in keeping Chavez' fight for farm worker's rights alive.

Martinez remained humble about his efforts throughout his life.

The community was invited to attend a public viewing for Martinez until 9 p.m. Wednesday at Porter Loring Mortuaries' north chapel.

As KENS 5 reported, Martinez passed away Sunday.

Raised on the west side of San Antonio, there's now a street named after him.

He was raised by migrant worker grandparents. Martinez became involved in activism after joining the International Brotherhood of Electrical Workers in 1966.

He organized marches and protests with local migrant farm workers, and recently mentored younger, undocumented immigrants fighting to stay in the U.S.

Martinez advocated to protect "sanctuary cities."

There will be a memorial procession on the west side Thursday, followed by a private funeral.
