Jerry is the founder and former moral leader at Shalhevet.
He did a one-year education degree at Harvard.
Harvard does have a copy, they might send it to your local library for interlibrary loan. Found your blog when trying to find Sam Gomberg’s location for an old acquaintance from Downers Grove South. Back in ancient times Sam was quite the hit with young women. Friedman information is:
A comparison of moral reasoning stage among Jewish day school and public school students / by Jerome Friedman.
viii, 137 leaves : ill. ; 29 cm.
Sam did have more than one good thing going for him–he married the most beautiful teacher I was ever cursed with having at Downers South–Donna Cameron.
