Arnold Neustadter,85, who invented the Rolodex card file to organize phone numbers, died Wednesday in New York.

His first successful invention was the spring-mounted personal phone directory that pops up at a given alphabet letter. He named the product Autodex.

In the 1940s, he and an engineer developed the famous cylindrical rotating file he called the Rolodex, which found its way into virtually every office in America.

His Zephyr American Corp. also is credited with some lesser-known products such as a Swivodex, which is a spill-proof inkwell, and Clipdex, a device stenographers could clip to the

knee as an aid in taking dictation.

Ronald Davies,91, a federal judge whose 1957 landmark civil rights decision required schools in Little Rock, Ark., to integrate, died Thursday in Fargo, N.D. He went into semi-retirement in 1971 and had several strokes in the late 1980s. The judge made history when, on a temporary assignment to Arkansas, he ruled in September 1957 that Little Rock schools must allow black students to attend.
