The first commercial circulating fluid bed reactor, PCLA #1 (Powdered Catalyst Louisiana), went on stream on May 25, 1942, in the Baton Rouge Refinery of the Standard Oil Company of New Jersey (now ExxonMobil Corporation). This first use of powdered catalysts in continuous operation allowed the efficient cracking of heavy gas oils to meet the growing demand for high-octane fuels. Today, fluid bed reactors are in use worldwide for the manufacture of fuels, chemical intermediates and plastics.

The plaque commemorating the development reads:

By the 1950s, synthetic fabrics - often wrinkle resistant and flame retardant - began to overtake cotton as the dominant U.S. textile fiber. To reverse this trend chemists and chemical engineers at the Southern Regional Research Center initiated research to modify cotton chemically. Their efforts in developing agents that crosslinked the cellulose fibers and in establishing crosslinking mechanisms led to improved durable press fabrics. SRRC studies also developed new agents that improved the durability of flame retardant cotton to laundering.

In the 1940s and 1950s, New Orleans experienced growth. Unfortunately, access from the north to the City continued to be limited by Lake Pontchartrain. Driving around the Lake was a time consuming effort. During this time period, a renewed interest developed to provide a direct connection across the center of the Lake to the north shore. As a result, the Greater New Orleans Expressway Commission was formed to build the Lake Pontchartrain Causeway Bridge. The original bridge (southbound) was opened on August 30, 1956.

Thomas Car Company

The St. Charles Avenue Streetcar Line is the oldest surviving interurban-urban passenger rail transportation system in the United States. Originally incorporated as the New Orleans Carrollton Rail Road in 1833, service began in 1835. A variety of motive power had been used including horses, mules, overhead cable, steam engines, and ammonia engines before electrification in 1893. The 900-series cars presently in service were designed and built by the Perley A. Thomas Car Company of High Point, North Carolina, in 1923 to 1924.

The city of Shreveport could not justify the cost of building a water distribution system solely for the purpose of supplying potable water. It was a series of disastrous fires in the 1880s that galvanized support for a pumping facility that would provide ample water for firefighting.

With a water table several feet below ground level, New Orleans faced a crisis after every heavy rainfall, not just through flooding but also through disease (yellow fever and malaria) caused by impure water. New Orleans was dependent on mechanical means for lifting water from its canals and sewage systems. A. Baldwin Wood (1879-1956), a young assistant city engineer, designed and installed a system of large screw pumps (axial flow machines) to syphon water and accelerate drainage. By 1915 the Wood screw pump became the most advanced drainage pump in use.
