Funeral services for former heavyweight boxing champion Joe Louis will be held at 10 a.m. Friday in the sports pavilion of Caesars Palace in Las Vegas, a hotel spokeswoman said.

Civil rights leader Rev. Jesse Jackson will deliver the eulogy.

Mr. Louis, 66, died of an apparent heart attack Sunday after he was admitted to Desert Springs Hospital.

Mr. Louis' body will lie in state at the sports pavilion from 10 a.m. to 9 p.m. Thursday, the spokeswoman added.

Burial will be at Palm Memorial Park in Las Vegas.

Mr. Louis, the longest reigning heavyweight champion in history, was remebered yesterday with respect and affection by national leaders and leading figures in the boxing community.

President Reagan said he was privileged to have had him as a friend.

"Outside the ring, he was a considerate and soft-spoken man," the president said. "Inside the ring, his courage, strength and consummate skill wrote a unique and unforgettable chapter in sports history.

"But Joe Louis was more than a sports legend. His career was an indictment of racial bigotry and a source of pride and inspiration to millions of white and black people around the world."

"He was the type of fighter every pro wanted to be," said Max Schmiling, the boxing hero of Nazi Germany in the 1930s and the only fighter ever to knock out Mr. Louis when the latter was in his prime.

"He was a boxing genius. We became very good friends. I was shocked and grieved by his death, although I cannot say it was unexpected."

In 1936 Schmeling knocked out Mr. Louis in a 12-round bout before the American had gained his title. But in a return match after Mr. Louis had become champion, he knocked out Schmeling in the first round on June 22, 1938 before a crowd of 70,000 at Yankee Stadium.

Buddy Baer, who fought Mr. Louis twice for the title and is now sergeant at arms for the California Legislature, described Mr. Louis as one of the all time great boxers.

"There was no doubt the Bomber was one of the best who ever came down the pike," said Baer. "But Father Time is reaping. He'll get us all sooner or later, won't he?"

Confined to a wheel chair in recent years, Mr. Louis had suffered a stroke and had been treated for heart trouble. Last December he underwent surgery to have a pacemaker implanted.

His last public appearance was Saturday night when he was wheeled into the sports pavilion at Caesars Palace just before the Larry Holmes-Trevor Berbick heavyweight title fight.

Former fighter Billy Conn of Pittsburgh, who fought Mr. Louis twice, said "We'll never see another one like him.

"Boxing didn't take its toll on Joe. No one was ever around long lenough to hit him that often. Old age caught him, that's all. He was the best boxer of all time."
