Diana MacArthur is a Santa Fe native. She was born at St. Vincent Hospital on Palace Avenue in 1933. Her parents, Elizabeth and Antonio "Tony" Taylor, were from East Texas. Her father was Lady Bird Johnson's brother. He was the first student at the Los Alamos Ranch School for Boys and later returned to the Santa Fe area as a tuberculosis patient.

MacArthur and her older sister, Gerry, were great friends of the three Ruthling children, Theo, Ford and Carlton. The sisters often stayed at the Ruthling ranch, where they slept outside in covered wagons, even in winter. The children all took dancing lessons from Jacques Cartier. MacArthur's parents divorced, and she lived with her father and her father 's wife, Matianna " Matti" Vigil.

Her mother married Charles Sibley, a career employee of United Fruit Company. The first time MacArthur and Gerry visited them in Guatemala, the girls were 7 and 14. They traveled alone, taking a train through the Mexican jungle , and crossing the river that was the border between the two countries in a dugout canoe.

On a later trip to visit her mother, MacArthur sailed in a United Fruit Company boat. When the boat docked in Havana, she toured the city by herself at age 12.

She attended Loretto Academy and Harrington Junior High, before going to boarding school in Pennsylvania. 

In 1955, she received a bachelor's degree in economics, with Phi Beta Kappa honors, from Vassar College.

She married and had her first child, Elizabeth in her senior year. Her husband, Nikolai Tschursin, was an emigre from the Soviet Union. Their son, Alexander, was born in Santa Fe.

The couple divorced after five years, and MacArthur raised her children as a single mother in Washington, D.C. She often spent time with her aunt Lady Bird and uncle Lyndon B. Johnson when he was speaker of the U.S. House of Representatives.

In 1962, MacArthur married Donald MacArthur, a Scottish scientist. He founded a firm, Dynamac, which she continued to run for 20 years after his death in 1988. She eventually sold the firm to another woman owned company.

When Lyndon B. Johnson was president, he appointed MacArthur to the President's Council on Youth Opportunity. Under President Bill Clinton, she served on a committee of advisers for science and technology that included the Massachusetts Institute of Technology president, three Nobel Prize winners, the president of Lockheed Martin and President Obama's current science adviser.

Today, MacArthur lives on a ridge overlooking Tesuque. "One always knows, if you are born in Santa Fe, where you will retire," she said.

Her son lives in Santa Fe, as does her grandson, Nikolas.

Her daughter died in 1994.

In reading the newspapers in Marshall Texas, there seems to be a lot of coming and going to Guatemala and Honduras, presumably to the United Fruit locations. In Passenger lists to these locations has turned up a lot of information.  Various family trees will be listed below but the name connections are really amazing:
