Cautious Comes Of Age By Gilbert Rogin, October 16, 1961 Cassius Clay, the heavyweight prodigy who is called Cautious by his trainer, was anything but in Louisville last week. He knocked out Alex Miteff and showed he can fight almost as much as he can talk.

The Eleven Men Behind Cassius Clay By Huston Horn, March 11, 1963 Innocent of prizefighting's bad old ways, these gentlemen hope by their example to put an end to the exploiting of boxers. They expect Clay to get rich� and to get a little bit richer themselves.

A Quick, Hard Right And A Needless Storm Of Protest By Tex Maule, June 7, 1965 Muhammad Ali (Cassius Clay) is a fighter bedeviled by his own excellence. He knocked out big Sonny Liston with a punch so marvelously fast that almost no one believed in it -- but it was hard and true.

The Wind That Blew In Chicago By William Barry Furlong, March 7, 1966 Cassius Clay was stage center as the Illinois commission reopened hearings on his fight with Ernie Terrell, but politicians (and 'patriots') were as much on trial as the champion.

A Case Of Conscience By Jack Olsen, April 11 1966 Call him Cassias Clay or Muhammad Ali, the Muslim name he prefers. He is the best-known athlete in the world. He is also the most hated, and an enigma even to those closest to him.

Learning Elijah's Advanced Lesson In Hate By Jack Olsen, May 2, 1966 It is difficult to see how Cassius Clay, who may have become a Black Muslim as early as 16, could have been kept out of the movement. Mystical, unsettled and obsessed with prophecy, he was a perfect prospect.

Taps For The Champ By Edwin Shrake, May 8, 1967 Muhammad Ali predicted great demonstrations, but they were mild (left). And so were the induction proceedings in Houston, where a calm military led Ali down the corridor to the room where he would make his fateful decision to reject the draft call.

"I Am Not Worried About Ali" By Bill Russell and Tex Maule, June 19, 1967 Earlier this month a group of prominent Negro athletes held a confidential meeting with Muhammad Ali in Cleveland to discuss his decision to reject Army service.

For Ali, A Time To Preach By Tex Maule, February 19, 1968 Whether sermonizing in California or at home, Muhammad Ali is still as controversial and colorful as he ever was in the ring� to which, he promises, he will return a winner from 'Alcatraz.'

Welcome Back, Ali! By Martin Kane, September 14, 1970 Overweight and undertrained, Muhammad still looked mighty good as he returned to action in Atlanta and worked up a sweat against three sparring partners. He could quickly get ready for the real thing.

No Requiem For A Heavyweight By George Plimpton, April 5, 1971 The fight, the dressing room, the hospital are all behind him. Now Muhammad Ali guides strangers through his new house, toys with its sparkling chandeliers and shows nothing has really changed.

Just Call Him Shubert Ali By Mark Kram, October 2, 1972 Bobbing out of reach or reaching out for Frazier, it was Broadway show biz for Muhammad.

Bury His Heart At Wounded Jaw By Dan Levin, April 9, 1973 Few saw the punch, but it was obvious that for all of Muhammad's courage a Whodoyoucallim named Norton had cracked his armor.

The Mouth That Nearly Roared By Tex Maule, April 23, 1973 His wired jaw kept the decibels down, but the message was clear: Norton, Frazier and Foreman are in trouble. Muhammad Ali will be 'trained' for this comeback and better than ever. That's what he says.

Jawful Test On The Mountain By Mark Kram, September 3, 1973 Muhammad Ali took it on the chin for real and felt no ill effects from his recent fracture. Training hard and seriously at his hillside retreat, he is still king of his clique and future champion of all he surveys.

Crafty Win For Muhammad By Mark Kram, February 4, 1974 There were no bombs in his fists, but with artfulness ripened through the years Ali took on all that Joe Frazier could offer and easily won their rematch.

Return Of The Big Bopper By George Plimpton, December 23, 1974 Down but determined to fight his way back to the top, Muhammad Ali turned 1974 into a year of great triumph.

"Lawdy, Lawdy, He's Great" By Mark Kram, October 13, 1975 Joe Frazier said that of Muhammad Ali, but so fierce and unsparing was their confrontation that the phrase could have applied to them both.

Oh, To Be Young And 200 Pounds By Mark Kram, May 31, 1976 With Muhammad Ali about to take his last bow, a bunch of pretenders are being groomed for a shot at the crown.

But Only A Farce In Tokyo By Mark Kram, July 5, 1976 Ballyhooed by promoters as The War of the Worlds, the Ali-Inoki fiasco ultimately proved to be the bore of the ages.

Not The Greatest Way To Go By Mark Kram, October 11, 1976 If, as Muhammad Ali maintains, his disputed victory over Ken Norton was his last fight ever, the faded image of his old skills that he left in the ring at Yankee Stadium makes his decision a wise one.

Through The Years With Ali By SI Staff, December 20, 1976 Out of Louisville he came, to become champion of the world� twice. Now Ali, whose worldwide celebrity may be unequaled in modern times, is near the end of his boxing career, and if no longer the greatest, he is still the best. He has quit, unquit and requit, the prerogative of the aging genius -- and the signal for a shuffle down memory lane. Here is a sampling of his life and times.

One More Time To The Top By Pat Putnam, September 25, 1978 Circling around a confused Leon Spinks, old master Ali jabbed a bit, grabbed a bit and won the world title all over again in their Battle of New Orleans.

Young Cassius Clay By William Nack, January 13, 1992 At 50, Muhammad Ali is a much-admired figure, just as he was in his formative years as a fun-loving but purposeful youth in Louisville.
