Early and personal life
Martha Isabel Ruiz Corzo was born on 17 January 1953 in Mexico City. She grew up in a wealthy family in Santiago de Querétaro in the central Mexican state of Querétaro. She is most often called "Pati", a nickname derived from the childhood nickname "pata" that her sister called her. Pati took up the violin at age 12, and as a teenager, she became the first violin in the Querétaro Philharmonic Orchestra, a position she held for five years. For 16 years, she taught music at the John F. Kennedy School in Querétaro. She married an economist named Roberto Pedraza Muñoz (born 1950) and had two sons, Roberto ("Beto") and Mario.
However, Ruiz Corzo eventually grew dissatisfied with modern city life.

Why this record matters

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 4, 2026. The linked authority identifier is Q25413242. VIAF identifies the subject as 11917507. The Library of Congress control number is no98016378. 1 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
