Candidate passages:
The last known survivor of the Yahi was named Ishi by American anthropologists.
Ishi had spent most of his life in hiding with his tribe members in the Sierra wilderness, emerging at the age of about 49, after the deaths of his mother and last relatives.
He was the only Yahi known to European-Americans.
Ishi emerged from the mountains near Oroville, California on August 29, 1911, having lived his entire life outside of the European-American culture.
Professors from the University of California, Berkeley read about him and brought him to San Francisco both for study and for his protection.
Called the "last wild Indian", he had been treated as a curiosity by the public.
Under the auspices of the anthropologist Alfred Kroeber, director of the Museum of Anthropology, Ishi lived there until his death from tuberculosis (then incurable) in 1916.
His language was studied in 1911 by the linguist Edward Sapir, who had previously done work on the northern dialects.
By tribal custom, he was not to reveal his name to an enemy.
Rather, one would be introduced by a friend, and then the name could be offered.
Since he was the last of his people, he had no friends, although he made some later at the University of California.
Tradition demanded that he never speak his name.
Researchers at the University of California, Berkeley gave him the name Ishi, the Yana word for "man".
He accepted this and adopted the term "Mr. Ishi" when he learned enough English.
Ishi worked as a research assistant at the Museum of Anthropology.
He taught Saxton Pope, a professor at the medical school and his physician, how to make arrows and bows, and to hunt with them.
Pope is considered to be the "father" of modern bow hunting, as he published extensively on techniques. 
Ishi is estimated to have been born between 1860 and 1862.
In 1865, when he was a young boy, Ishi and his family were attacked in the Three Knolls Massacre, in which 40 of their tribesmen were killed.
Approximately 30 Yahi survived to escape, but shortly afterwards, cattlemen killed about half of the survivors.
The last survivors, including Ishi and his family, went into hiding for the next 40 years, and their tribe was popularly believed to be extinct.
Richard Burrill wrote, in "Ishi Rediscovered": "In 1865, near the Yahi’s special place, Black Rock, the waters of Mill Creek turned red at the Three Knolls Massacre.
'Sixteen' (Moak 1923:20) or 'seventeen' (T. Kroeber 1961: 80) [so-called] Indian fighters killed about forty Yahi, as part of a retaliatory attack for two white women and a man killed at the Workman’s household on Lower Concow Creek near Oroville (Moak 1923:18).
Eleven of the Indian fighters that day were Robert A. Anderson, Hiram Good, Sim Moak, Hardy Thomasson, Jack Houser (also spelled Howser by Anderson), Henry Curtis (leader of the Concow men), his brother Frank Curtis, as well as Tom Gore, Bill Matthews, and William Merithew.
W. J. Seagraves visited the site, too, but some time after the battle had been fought (Waterman 1918: 53).
"Burrill continued, "Robert Anderson (1909:79) wrote, 'Into the stream they leaped, but few got out alive.
Instead many dead bodies floated down the rapid current.'
One captive Indian woman named Mariah from Big Meadows (Lake Almanor today), was one of those who did escape (Burrill, 2003:39).
The Three Knolls battle is also described in Theodora Kroeber’s "Ishi in Two Worlds" (1961: 81-82), but more information has come to light.
It is estimated that with this massacre, Ishi's entire cultural group, the Yana/Yahi, may have been reduced to about sixty individuals.
From 1859 to 1911, Ishi's remote band became more and more infiltrated by non-Yahi Indian representatives, such as Wintun, Nomlaki and Pit River individuals.
In 1879, the infamous Indian boarding schools started in California.
The ranks of embittered reservation renegades who became the new 'boys in the hills', to quote Robert Anderson, became a direct function of what new attacks or removal campaigns that the volunteers and military troops elected to carry out against the northern California Indian tribes during that time.
"In late 1908, a group of surveyors came across the camp inhabited by a man, a young girl, and an elderly native woman — Ishi, his younger sister, and his elderly mother, respectively.
The former two fled while the latter hid herself in blankets to avoid detection, as she was sick and unable to flee.
The surveyors ransacked the camp and took everything.
Ishi's mother and other relatives died soon after Ishi's return. 
Ishi (c. 1860 – 1916) was an American Indian thought to be the last of the Yahi tribe.
Ishi may also refer to: Eshraque "iSHi" Mughal (born 1981), Swedish music producer and songwriter "", TV-film on the Indian Ishi, 1978 Ishi Press, Japanese publishing company focused on the game Go  
The medical school where Pope taught was located near the museum where Ishi worked as a janitor, having been brought there for study by Professor T. T. Watterman of the University of California Department of Anthropology.
Because Ishi had grown up in the isolated Yahi tribe, he had little immunity to diseases, and Pope met Ishi during his stays at the University hospital.
Pope learned some of the Yahi language, and spent much time with Ishi, learning of his life and listening to the Yahi tribal folklore.
Ishi taught Pope how to make bows and arrows as the Yahi did, and how to hunt with them.
Pope and Ishi remained close until Ishi's death from tuberculosis in 1916.
In spite of this close relationship and against the fervently stated wishes of his Yahi friend, Pope insisted that Ishi be autopsied after death and his brain removed. 
 "Ishi", the last surviving member of the Yahi American Indian tribe and last speaker of the Yana language, was discovered hiding in a corral near Oroville, California.
Ishi lived the rest of his life as the guest of Professor Alfred Kroeber, curator of the Museum of Anthropology in San Francisco, and died in 1916.
Died: Mahbub Ali Khan, Asaf Jah VI, 45, richest prince of the Indian Empire.
As the Nizam of Hyderabad, he had an income of $10,000,000 a year and ruled over 11 million subjects.
He was succeeded by his 25 year old son, Osman Ali Khan.
