Final answer:
Lady Bird Johnson was born on December 22, 1912, in Karnack, Texas. She was well-known for her environmental beautification efforts and contributions to children's education through the Head Start program. The Voting Rights Act was signed not by any of the first ladies mentioned, but by her husband, President Lyndon B. Johnson.
Step-by-step explanation:
The individual who was born on December 22, 1912, in Karnack, Texas, is Lady Bird Johnson. Lady Bird Johnson, born Claudia Alta Taylor, was the wife of Lyndon B. Johnson, the 36th President of the United States. As First Lady, she was known for her advocacy for beautifying the nation's cities and highways and the Head Start program. The Voting Rights Act, which is another significant aspect of Lyndon Johnson's presidency, was signed by him, not John F. Kennedy, Barack Obama, or Franklin D. Roosevelt, as listed in the provided options.
Lady Bird Johnson succeeded Eleanor Roosevelt and Jacqueline Kennedy Onassis in her role. Eleanor Roosevelt played a substantial role in championing civil rights during her tenure as First Lady, and Jacqueline Kennedy Onassis was noted for bringing a sense of style and historic preservation to the White House. Moreover, Betty Ford also made notable contributions in her time, such as her support for the Equal Rights Amendment.
