The former president is often remembered for his altruism. His daughter Dorothy Bush Koch, 60, and son Neil Bush, 64, told PEOPLE on Friday that their family hopes to honor his “legacy of unrelenting service to others” on the anniversary of his death.

The pair added: “In his honor, we ask and encourage people of all ages and backgrounds to think of how they can be a point of light and inspiration in their own community and help transform the world into one in which no one sits on the sidelines.”

The “point of light” phrase was a signature of the 41st president’s administration, along with the thousand-plus commendations he gave to individuals and organizations. These daily “Points of the Light” awards later gave rise to thePoints of Light Foundationin 1990, which Neil now chairs.
