That’s only one of the cherished myths that Don Lattin debunks in “The Harvard Psychedelic Club: How Timothy Leary, Ram Dass, Huston Smith and Andrew Weil Killed the Fifties and Ushered in a New Age for America” (HarperOne: $24.99).

On the wall of my home office is an authentic family relic — a tallis bag that was carried from Byelorussia to Ellis Island by my wife’s grandfather, Ben Zion Benjamin.
