Mother lode is a principal vein or zone of veins of gold or silver ore. The term probably came from a literal translation of the Spanish veta madre, a term common in old Mexican mining. Veta madre, for instance, is the name given to an 11-kilometre-long (6.8 mi) silver vein discovered in 1548 in Guanajuato, New Spain (modern-day Mexico).

In the United States, Mother Lode is most famously the name given to the long alignment of hard-rock gold deposits stretching northwest to southeast in the Sierra Nevada of California. The California Mother Lode is a zone from 1.5 to 6 kilometres (0.93 to 3.7 mi) wide and 190 kilometres (120 mi) long, extending from Georgetown in El Dorado County on the north, through Amador, Calaveras, and Tuolumne counties, south to Mormon Bar in Mariposa County. It was discovered in the early 1850s, during the California gold rush. Following the elucidation of the theory of plate tectonics, the Mother Lode was found to coincide with the suture line of a terrane, the Smartville Block. The zone contains hundreds of mines and prospects, including some of the best-known historic mines of the gold-rush era. Individual gold deposits within the Mother Lode are gold-bearing quartz veins up to 15 metres (49 ft) thick and a few thousand feet long. The California Mother Lode was one of the most productive gold-producing districts in the United States. Now it is known as a destination for tourism.

Charlton Heston (born John Charles Carter; October 4, 1923 – April 5, 2008) was an American actor of film, theatre and television. Heston is known for heroic roles in films such as The Ten Commandments, Ben-Hur for which he won the Academy Award for Best Actor, El Cid, and Planet of the Apes. He also is well known for his roles in the films The Greatest Show on Earth and Touch of Evil.

Heston was also known for his political activism. In the 1950s and 1960s he was one of a handful of Hollywood actors to speak openly against racism and was an active supporter of the Civil Rights Movement. Initially a moderate Democrat, he later supported conservative Republican policies and was president of the National Rifle Association from 1998 to 2003.

Heston was born John Charles Carter, the son of Lilla (née Charlton; 1899–1994) and Russell Whitford Carter (1897–1966), a sawmill operator. Most sources state that he was born in Evanston, Illinois. Heston's autobiography, however, and some other sources place his birth in No Man's Land, Illinois, which usually refers to a then-unincorporated area now part of Wilmette, a wealthy northern suburb of Chicago. Heston said in a 1995 interview that he was not very good at remembering addresses or his early childhood.

James Joseph Brown (May 3, 1933 – December 25, 2006) was an American singer, songwriter, musician, and recording artist. He is the originator of funk music and is a major figure of 20th century popular music and dance.

In a career that spanned decades, Brown profoundly influenced the development of many different musical genres. Brown moved on a continuum of blues and gospel-based forms and styles to a profoundly "Africanized" approach to music making. Brown performed in concerts, first making his rounds across the Chitlin' Circuit, and then across the country and later around the world, along with appearing in shows on television and in movies. Although he contributed much to the music world through his hitmaking, Brown holds the record as the artist who charted the most singles on the Billboard Hot 100 without ever hitting number one on that chart.

For many years, Brown's touring show was one of the most extravagant productions in American popular music. At the time of Brown's death, his band included three guitarists, two bass guitar players, two drummers, three horns and a percussionist. The bands that he maintained during the late 1960s and 1970s were of comparable size, and the bands also included a three-piece amplified string section that played during ballads. Brown employed between 40 and 50 people for the James Brown Revue, and members of the revue traveled with him in a bus to cities and towns all over the country, performing upwards of 330 shows a year with almost all of the shows as one-nighters. In 1986, he was inducted into the Rock and Roll Hall of Fame and in 1990 into the Songwriters Hall of Fame.
