Hall of Fame pitcher Sandy Koufax. Actor KevinBacon. World Trade Center developer Larry Silverstein.

All three have at least one thing in common: Their names appearon a list of several thousand clients who lost money investing withBernard Madoff that have been made public in a court filing in U.S.Bankruptcy Court in Manhattan.

The list emerged late Wednesday, shortly after a whistleblowerin the case, Harry Markopolos, told House lawmakers at a hearingthat he had discovered that additional funds had relayedinvestments to Madoff in Europe - and that the managers of these"feeder" funds may have ignored signs of the massive fraudscheme.

He plans to present his findings to the Securities and ExchangeCommission's inspector general Thursday. If proven, they wouldsubstantiate the assertions of many analysts that the alleged fraudwas far too large for Madoff to have conducted alone.

House lawmakers on Wednesday also sparred with SEC officials,accusing them of impeding their probe into how the agency failed touncover the alleged fraud.

Prosecutors say Madoff admits he lost more than $50 billionbelonging to investors. Defense lawyers say he has cooperated withauthorities to help identify assets.

The list of client names, including those of Madoff's relatives,numerous celebrities, dead people and charitable institutions, arelisted on a 162-page document. Each page carries 84 single-spacedlines. Some customers are listed multiple times, presumably becausethey had multiple accounts.

The customers include prominent people and institutions thatalready had been publicly revealed, such as the Wilpon family,owner of the New York Mets.

Also listed were more than two dozen accounts involving the Metsand companies affiliated with their owners were listed, many withaddresses at Shea Stadium.

The amount each person or institution invested with Madoff isn'tlisted.

One client is Ira Sorkin, the attorney who's defending Madoffagainst charges he perpetrated the biggest financial fraud inhistory. Others include Madoff's wife, sons, brother and otherrelatives.

The list was compiled by AlixPartners LLP, a Dallas companyhired as claims agent by the trustee overseeing the liquidation ofBernard L. Madoff Investment Securities LLC.

Madoff hasn't been indicted. He's being held under house arrestat his multimillion-dollar penthouse.
