Riccardo worked as an accountant at
Touche, Ross, Bailey, & Smart until 1959, when he joined another of the firm's former accountants,
Lynn A. Townsend, at the Chrysler Corporation, as a financial officer. He moved quickly through the ranks, becoming a vice president of
Chrysler Canada in 1961, sales manager of the
Dodge division in 1966, assistant general manager of Dodge in 1964, assistant general manager of
Chrysler–
Pontiac in 1965, and group vice president for domestic automotive operations later that same year. In 1970,
Virgil Boyd was ousted as president (receiving the new title of vice-chairman) amid lagging sales and earnings, in favor of Riccardo. In this role, Riccardo was "in charge of all corporate operations" and was the number two officer in the company behind chairman and CEO Lynn Townsend. On July 8, 1975, Chrysler announced that Riccardo would succeed the retiring Townsend effective October 1. Riccardo took over a company that was struggling due to the
1973 oil crisis and
1973–1975 recession. Under his leadership the company disposed of a number of its unprofitable subsidiaries, including
Chrysler Europe,
Airtemp, and
Big Sky Resort. It also sold its unfinished
Westmoreland Assembly to
Volkswagen. He reduced the size of Chrysler's car inventory, which had left the manufacturer with $200 million in unsold vehicles during the recession. In 1978, Chrysler brought on recently dismissed
Ford president
Lee Iacocca to help turn around the struggling auto maker. In 1979, Chrysler sought assistance from the federal government. On September 17, 1979, Riccardo announced his resignation – citing poor health and his belief that the company would be more likely to receive government aid under new management. His retirement took effect three days later and he was succeeded by Iacocca. Following Riccardo's departure, Chrysler received $1.5 billion in federal loans, which it paid off seven years early. ==Later life==
