In the 1930's, the Great Depression brought real estate activity and Central's business to a standstill. A resourceful Maury Rivkin was able to supplement his income by promoting dances and prize fights. His fight cards were also first rate featuring top talent such as future boxing champions Joe Louis and Tony Zale. As the decade of the 1940's began, the economy and Central both rebounded.
During the 1950's and the 1960's, a new generation of sleek, modern skyscrapers incorporating large aluminum frame windows in their exposed concrete or metal exteriors dramatically changed the skyline.
Charles Rivkin, Maury's son, whose background was in business and law, joined Central in 1960. He soon became its president and continued to lead the company for more than forty years. The decade of the 1960's was one of great technological change in construction and repair, and Central, again broadened the scope of its services.
Age and years of penetrating weather were taking an increasing toll on subsurface structural elements of many of the city's venerable buildings. During the 1970's and 80's, the focus of the tuck pointing industry shifted to address the damaging effects of rust weakened supporting steel within the walls. Central added a structural engineer to its staff and created a new division specializing in the expertise of façade forensics and the techniques required to restore and repair the city's aging structures.
Central's expansion presaged Chicago's enactment of its first Façade Repair Ordinance in 1978, the city's response to a series of wall collapses. Although short-lived, the ordinance, which established responsibility for façade evaluation in structural engineers and architects, fundamentally changed the way in which the tuck pointing industry did business.
