Richard Herzberg, the only Jewish hostage on TWA Flight 847 last month who was taken away by Shiite radicals of the Hezbollah faction, appeared with his wife Sue Ellen yesterday at B'nai B'rith headquarters here in the same room where 130 people were held hostage by Hanafi Muslims in 1977.

The Herzbergs praised Uli Derickson, Flight 847's purser, for her actions to protect them and the other passengers as the hijackers tried to single out those with Jewish-sounding names and members of the U.S. military.

The Herzbergs were on their honeymoon from Norfolk when the Athens-to-Rome flight was hijacked June 14. At the time, Sue Ellen Herzberg said yesterday, she was wearing a gold wedding band with an inscription in Hebrew, "I am my beloved's and my beloved is mine."

She said she hid it in her purse, which was taken by the hijackers and never returned. The hijackers, she said, tried to find the owners of the ring and other items with Jewish connotations, but apparently were thwarted at least in part by Derickson.

The Herzbergs praised B'nai B'rith for its aid to their family during the 17-day ordeal
