Engineer and Inventor
Frank Sordello, 62, an engineer who held 44 high-tech patents, including one for an electronic tachometer that proved fundamental for the operation of computer disk drives, died of colon cancer June 6 in Los Gatos, Calif.
Mr. Sordello began his career at IBM in 1960, leaving to become co-founder and chief engineer of Information Storage Systems, a disk-drive maker that was acquired by Sperry-Univac.
From 1973 to 1975, he served on a Commerce Department advisory committee on computer peripherals and components.
In 1978, he helped establish one of the applied-research centers at Memorex and was named a corporate vice president and a Memorex fellow the following year.
Carmen Perry, 93, whose 1975 translation of a Mexican officer's memoir, "With Santa Anna in Texas: Diary of Jose Enrique de la Pena," with its controversial description of the capture and execution of Davy Crockett at the Alamo, died June 18 in San Antonio. The cause of death was not reported.
The account says that, on Santa Anna's orders, Crockett and the others were stabbed with bayonets and shot, rather then dying in combat. When the book appeared, Ms. Perry received threatening mail and phone calls from people who questioned why she was dishonoring the Texas hero.
Ms. Perry held a master's degree in Spanish literature from the University of Texas. She became a leading translator and researcher at the Daughters of the Republic of Texas Library at the Alamo, where she worked from 1959 to 1968.
