As the anniversary of the attack approaches his relatives and friends said they always described him as a “mensch” – a Yiddish word for a person of decency who shows up and takes responsibility for those around them.
Cravitz’s stepdaughter, Sherelle Dresner, wants 2 October to become National Mensch Day and is setting up a charity, Mensch Like Melvin, to create a lasting legacy.
Dresner, from Bury, Greater Manchester, said: “One year on our grief is still raw and the pain has not lessened.
“But the months following Melvin’s murder have strengthened our commitment to putting good into the world, in whatever shape that may be.
“Being a mensch transcends religion, background, and identity. It just means being a good person.
“It can be checking on a neighbour, holding a door for someone struggling, volunteering your time for someone – something that is right, kind, and decent.
“Anyone can be a mensch. On 2nd October, in memory of Adrian and Melvin, please be one.”
Inquests into their deaths will be held on a date to be fixed next year.
