Schnader Harrison Segal & Lewis is one of the law firms that the Philadelphia School Reform Commission keeps on retainer. The firm will soon wind down its operations and dissolve itself after nearly 90 years. Philadelphia-based law firm Schnader Harrison Segal & Lewis said Thursday that it is dissolving after nearly 90 years in business. The 91-lawyer firm in a statement said that it will continue "to provide uninterrupted service" to clients as it unwinds. Leslie Corwin, a Duane Morris lawyer who is advising Schnader on its dissolution, said the firm's equity partnership is poised to vote on the wind-down plan. Schnader Harrison has offices in Philadelphia, Cherry Hill, New Jersey, New York, Pittsburgh, San Francisco and Wilmington. It also operated in Jakarta through an association with Indonesian law firm Yang & Co. The firm said it was co-founded in 1934 by former Pennsylvania Attorney General William Schnader. Schnader wanted to return to private practice at his old firm but was unable to bring his protege, Bernard Segal, because Segal was Jewish. Schnader, Segal and Francis Lewis, a law school colleague of Schnader's, founded Schnader & Lewis.
