Carlos Flores Truan (June 9, 1935 – April 10, 2012) was a businessman from Corpus Christi, Texas, who served for thirty-four years as a Democrat in both houses of the Texas State Legislature. He was a state representative from 1969 to 1977 and a state senator from 1977 to 2003 in Nueces County.
First elected in 1968, Truan served four terms in the Texas House. He was elected to the Senate in 1976. In 1985, he was elected by his senatorial colleagues as President Pro Tem and honored as Governor-for-a-Day. Truan served longer than any other member of the Texas Senate. In 1995, he became the first Hispanic to serve as Dean of the Texas Senate.
As a representative, Truan uncovered institutional child care abuses in Texas and wrote the Texas Child Care Licensing Act of 1975. He was also the sponsor of the Texas Public Housing Authority Act (1969), the Texas Bilingual Education Act (1969), the Texas Adult Education Act (1973), and the Interstate Placement of Children Act (1975).
Truan is the only member of the Texas Legislature who participated in both major insurgencies of contemporary Texas history, the “Dirty Thirty” ethics coalition of 1971 and the “Killer Bees” in 1979. The “Dirty Thirty” consisted of thirty reform-minded representatives who stood firmly in favor of a full investigation of the Sharpstown bank scandal. The “Killer Bees” were twelve senators who prevented the Senate from having a quorum to adopt legislation that would have impacted the presidential primary election of 1980 in Texas.
Truan worked to enact a law to organize a birth defects registry. He was also involved in the establishment of a Texas coastal management program and the enactment of the Coastal Dome Protection Act, the Oil Spill Prevention and Response Act, and legislation to regulate plumbing fixtures. Some of Truan's most noted contributions were in stopping bills that would have reduced landfill standards, abridged local control of habitat conservation plans, or harmed the ability of citizens to participate in the state regulatory process.
After he left the state Senate early in 2003, Truan engaged in his insurance business in Corpus Christi, where he died in the spring of 2012 at the age of seventy-six.
