Explanation:

The family’s leaders have pulled off three of the great marketing triumphs of the modern era: The first is selling OxyContin; the second is promoting the Sackler name; and the third is ensuring that, as far as the public is aware, the first and the second have nothing to do with one another.

To the extent that the Sacklers have cultivated a reputation, it’s for being earnest healers, judicious stewards of scientific progress, and connoisseurs of old and beautiful things.

The Sackler brothers came from a family of Jewish immigrants in Flatbush, Brooklyn. Arthur was a headstrong and ambitious provider, setting the tone—and often choosing the path—for his younger brothers. After attending medical school on Arthur’s dime, Mortimer and Raymond followed him to jobs at the Creedmoor psychiatric hospital in Queens. There, they coauthored more than one hundred studies on the biochemical roots of mental illness. The brothers’ research was promising—they were among the first to identify a link between psychosis and the hormone cortisone—but their findings were mostly ignored by their professional peers, who, in keeping with the era, favored a Freudian model of mental illness.
