Question:
Grace Brewster Murray Hopper (nee Murray; December 9, 1906 - January 1, 1992) was an American computer scientist and United States Navy rear admiral. One of the first programmers of the Harvard Mark I computer, she was a pioneer of computer programming who invented one of the first compiler related tools. She popularized the idea of machine-independent programming languages, which led to the development of COBOL, an early high-level programming language still in use today. Hopper had attempted to enlist in the Navy during World War II, but she was rejected by the military because she was 34 years of age and thus too old to enlist.
Throughout much of her later career, Hopper was much in demand as a speaker at various computer-related events. She was well known for her lively and irreverent speaking style, as well as a rich treasury of early war stories. She also received the nickname "Grandma COBOL". While she was working on a Mark II Computer at a US Navy research lab in Dahlgren, Virginia in 1947, her associates discovered a moth that was stuck in a relay; the moth impeded the operation of the relay. While neither Hopper nor her crew mentioned the phrase "debugging" in their logs, the case was held as an instance of literal "debugging." For many years, the term bug had been in use in engineering. The remains of the moth can be found in the group's log book at the Smithsonian Institution's National Museum of American History in Washington, D.C. Grace Hopper is famous for her nanoseconds visual aid. People (such as generals and admirals) used to ask her why satellite communication took so long. She started handing out pieces of wire that were just under one foot long (11.80 inches = 300 millimeters)--the distance that light travels in one nanosecond. She gave these pieces of wire the metonym "nanoseconds." She was careful to tell her audience that the length of her nanoseconds was actually the maximum speed the signals would travel in a vacuum, and that signals would travel more slowly through the actual wires that were her teaching aids. Later she used the same pieces of wire to illustrate why computers had to be small to be fast. At many of her talks and visits, she handed out "nanoseconds" to everyone in the audience, contrasting them with a coil of wire 984 feet long, representing a microsecond. Later, while giving these lectures while working for DEC, she passed out packets of pepper, calling the individual grains of ground pepper picoseconds. Jay Elliot described Grace Hopper as appearing to be "'all Navy', but when you reach inside, you find a 'Pirate' dying to be released".

Question:
Clara Ann Fowler was born on November 8, 1927, in Claremore, Oklahoma (although some sources give Muskogee) into a large and poor family. Her father, B.A. Fowler, worked on the MKT railroad, while her mother, Margaret, and older sisters picked cotton. As she recalled on television many years later, the family lived without electricity, and therefore she could not read after dark. She was raised in Foraker, Hardy, Muskogee and Avant, Oklahoma, before attending Daniel Webster High School in Tulsa, from which she graduated in 1945.
Patti Page recorded several songs with Al Clauser & His Oklahoma Outlaws (1946), The Eddie Getz Orchestra, and the George Barnes Trio (1947). Page recorded her first hit single, "Confess", in 1947. Because of a strike, background singers were not available to provide harmony vocals for the song, so Page and the label decided to overdub the harmony parts. Bill Putnam, an engineer for Mercury Records, was able to overdub Page's voice, using the latest recording technology. Thus, Page became the first pop artist to harmonize her own vocals on a recording. This technique would later be used on Page's biggest hit singles in the 1950s. In 1948, "Confess" became a Top 15 hit on Billboard magazine, peaking at No. 12 on the "Best-Sellers" chart, becoming her first hit. Page followed the single with four more in 1948-1949, only one of which was a Top 20 hit, "So in Love" (1949). Page also had a Top 15 hit on the Billboard magazine country chart in 1949 with "Money, Marbles, and Chalk". In 1950, Page had her first million-selling single "With My Eyes Wide Open, I'm Dreaming", another song where she harmonized her vocals. Because she was overdubbing her vocals, Page's name had to be listed on the recording credits as a group. According to one early-1950s' chart, Page was credited as "The Patti Page Quartet." In mid-1950, Page's single, "All My Love (Bolero)" peaked at No. 1 on Billboard magazine, becoming her first No. 1 hit, spending five weeks there. That same year, she also had her first Top 10 hit with "I Don't Care if the Sun Don't Shine", as well as the Top 25 single, "Back in Your Own Backyard".

What happened afterwards?

Answer:
