People from San Antonio

Vivian Distin (née Liberto, formerly Cash; April 23, 1934 – May 24, 2005) was an American homemaker and author. She is notable as the first wife of singer Johnny Cash and mother of their four daughters. She inspired his first hit single "I Walk the Line".Born and raised in San Antonio, Texas, she grew up in Sicilian-American culture and was raised Catholic. Following her marriage to Cash in Texas, she was subject to controversy in 1965-1966 related to her racial identity because of publicity after her husband's arrest for drug possession. White supremacists, judging by her appearance in a widely published photo, claimed that she was black and thus married illegally to her husband. She and her husband were subject to harassment and he was boycotted for a year in the South before his manager documented her background as white.
After the couple divorced in 1966, they each married again. Cash had chief responsibility for raising their daughters. They typically spent time in the summer with their father and stepmother, both singer/songwriters.
In 2007 Distin published a memoir, prepared with Ann Sharpsteen, under her former married name of 'Vivian Cash'. It was based on her years with Johnny Cash and their many letters before their marriage.

Marshall Conring Johnston (born May 10, 1930) is an American botanist who made several explorations in Mexico and specialized in plants in the family Gesneriaceae.
Johnston was born in San Antonio in the family of Theodore Harris Johnston and Lucile Mary Conring. He went on his first botanical expeditions to Mexico while still in high school during 1945-1947. On those trips he visited the northern Mexican states of Tamaulipas, Nuevo Leon, Coahuila, Durango, and Zacatecas. From 1972-1974 he made trips to Chihuahua, concentrating on desert flora. These early 1970s trips resulted in the bulk of his botanic collection. Marshal participated in the creation of the books Flora of Texas, Flora of North America, and Flora Neotropica. Johnston was also a professor at the University of Texas at Austin.

Martha E. Bernal (April 13, 1931, San Antonio, Texas – September 28, 2001) was an American clinical psychologist. She earned her doctoral degree at Indiana University Bloomington in 1962. She was the first Latina to receive a doctorate degree in psychology in the United States. She helped with the treatment and assessment of children with behavioral problems and worked to develop organizations that have a focus on ethnic groups.

Daniel Meyer (February 6, 1932 – May 16, 1998) was the founder and president Southwest Technical Products Corporation. He was born in New Braunfels, Texas, and raised in San Marcos, Texas, where he earned a bachelor's degree in mathematics and physics in 1957 from Southwest Texas State. After college he married Helen Wentz, moved to San Antonio and became a research engineer in the electrical engineering department of Southwest Research Institute.
He soon started writing hobbyist articles. The first was in Electronics World (May 1960) and later he had a two part cover feature for Radio-Electronics (October, November 1962). The March 1963 issue of Popular Electronics featured his ultrasonic listening device on the cover. The projects would often require a printed circuit board or specialized components that were not available at the local electronics parts store. Readers could purchase them directly from Dan Meyer.Dan Meyer saw the business opportunity in providing circuit boards and parts for the Popular Electronics projects. In January 1964 he left Southwest Research Institute to start an electronics kit company. He continued to write articles and ran the mail order kit business from his home garage in San Antonio, Texas. By 1965 he was providing the kits for other authors such as Lou Garner. In 1967 he sold a kit for Don Lancaster's "IC-67 Metal Locator". In early 1967 Meyer moved his growing business from his home to a new building on a 3-acre (12,000 m2) site in San Antonio. The Daniel E. Meyer Company (DEMCO) became Southwest Technical Products Corporation (SWTPC) that fall.The concept of selling a kit based on a magazine article had been around since the early days of radio. Daniel Meyer perfected the process. In 1967, Popular Electronics had six articles by Dan Meyer and four by Don Lancaster. Seven of that year's cover stories featured kits sold by SWTPC. In the years 1966 to 1971, SWTPC's authors wrote 64 articles and had 25 cover stories in Popular Electronics. (Don Lancaster alone had 23 articles and 10 were cover stories.) The San Antonio Express-News did a feature story on Southwest Technical Products in November 1972. "Meyer built his mail-order business from scratch to more than $1 million in sales in six years." The company was shipping 100 kits a day from 18,000 square feet (1,700 m2) of buildings.In the first ten years, SWTPC's most popular products were audio kits followed by test equipment. There was also typical 1970s products like color organs that would synchronize colored lights with music as well as strobe lights. Dan Meyer developed a series of very low intermodulation (IM) distortion audio power amplifiers known as Tigers, many still in use today. Don Lancaster developed a series of decimal readout counters and voltmeters that used the latest technology.
In mid 1975 Dan Meyer asked one of his engineers, Gary Kay, to design a computer based on the Motorola 6800 design kit. The first deliveries were in November 1975. In June 1976 SWTPC introduced the AC-30 Cassette Interface for data storage and the PR-40 printer. One could now purchase a complete computer system for about $1500.Many of the early hobbyist computer companies were founded by engineers who did not know how to run a business. They would fold in a year or so. SWTPC had been successful in the kit business for over a decade so they could deliver working products.
Floppy Disk systems, full feature terminals, and many peripherals were added in 1977. The bus structure was called the SS-50 and soon many other vendors were making add-in cards and complete systems. In 1979 SWTPC introduced a new line based on the Motorola 6809 processor. These systems were produced until the mid-1980s. By then, the IBM PC was dominating the personal computer world and SWTPC shifted to point of sale (POS) systems.

He studied journalism at University of Notre Dame.From 1953, he was the publisher and editor of La Opinión, a Spanish language newspaper based in Los Angeles that his father founded in 1926. In 1964, President Lyndon B. Johnson appointed Lozano as a consultant to the United States Department of State. He also served on the California advisory committee to the United States Commission on Civil Rights.Lozano held directorships at Bank of America, The Walt Disney Company, Pacific Life, and Sempra Energy, and was a member of the Council of American Ambassadors.

James Robert Cade (September 26, 1927 – November 27, 2007) was an American physician, university professor, research scientist and inventor. Cade, a native of Texas, earned his bachelor and medical degrees at the University of Texas, and became a professor of medicine and nephrology at the University of Florida. Although Cade engaged in many areas of medical research, he is most widely remembered as the leader of the research team that created the sports drink Gatorade. Gatorade would have significant medical applications for treating dehydration in patients, and has generated over $150 million in royalties for the university.
In his later years, Cade became a prominent philanthropist, donating significant sums to charities affiliated with the Lutheran Church, creating scholarships and donating freely to the University of Florida and other colleges and universities, and endowing his own charitable foundations.
