The Compound Trump Squeeze is one of the oldest
squeezes formulated by the Whist player Mr. William Whitfield before the turn of the 20th century, that is before 1900.
There is very little information available about this gentleman, but it is believed that he was the Captain William Whitfield of the whaling ship John Howland, who rescued five shipwrecked Japanese fishermen in the year 1841. One of those rescued was named Manjiro Nakahama, who became the first Japanese person to actually reside in the United States of America after Captain William Whitfield accepted him into his home in Fairhaven, Massachusetts, United States.
The photograph below is a portrait of Captain William Whitfield. However, there can be no positive evidence produced that Captain William Whitfield is indeed the Whist person, who discovered the Compound Trump Squeeze.
Note: Any additional information regarding Mr. William Whitfield would be greatly appreciated.
Mr. William Whitfield defined a Compound Trump Squeeze as a squeeze in which at least one opponent is subject to a trump squeeze. The following illustration should suffice to clarify his definition.
The situation is that South is the declarer. The trump suit is Spades. South is on lead. South needs all the remaining tricks to fulfill the contract.
South leads a low Heart and trumps in dummy. A trump is lead from dummy, and East discovers that he must discard a Club or a Diamond to avoid allowing Declarer to establish an additional Heart trick by ruffing.
South then discards that suit which East discards. A Diamond for a Diamond, or a Club for a Club. Whichever suit East discards, South discards, and South then leads that suit from the dummy and wins in his hand. If East discards a Diamond, South then leads a Diamond from the dummy, and wins with the King of Diamonds in his hand. If East discards a Club, then South leads a Club from the dummy, and wins the trick with the Ace of Clubs.
South then leads the Ace of Hearts, discards a Diamond from dummy, and leads another small Heart, which South ruffs in dummy.
When South leads the last trump card from the dummy, it becomes obvious to East that he must keep his last Heart and discard whichever Minor suit he has kept. South discards his last Heart on the last trump card, and then West is compound trump-squeezed in both Minor suits.

The Whitfield Six - by William Whitfield
The trump suit is established as Hearts. South is on lead and must win all remaining tricks. This is the complete double dummy puzzle as presented by Mr. William Whitfield.
Solution to the Play
South leads the 
Jack, and unblocks the eight-spot. On the next trick a Spade is ruffed. Then declarer plays dummy's last Heart (the trump suit).
South drops the 
Queen and East also discards his last Diamond. West, however, is forced to guard the Diamond suit. Since a discard in the Club suit would enable a finesse in that suit, West is forced to throw his remaining Spade. Now the Ace squeezes East in both black suits.
The Whitfield Eight - by William Whitfield
The following two bridge articles coined by Mr. Willaim Whitfield have been preserved for posterity on the website of Mr. Ted Muller. The frist article has been titled The Whitfield Eight. Source. This article has only been preserved and archived on this site for future reference. The origin of this double dummy puzzle is unknown.
The trump suit is established as Spades. South is on lead and must win all remaining tricks. This is the complete double dummy puzzle as presented by Mr. William Whitfield.
Solution to the Play
South trumps a Club, then leads a Spade. East must hold onto Clubs to prevent establishment of declarer's long card, so he discards a red suit - say, Hearts. South also sheds a Heart, then plays a Heart to the Ace. The Ace is cashed, discarding a Diamond from dummy, and a Club is ruffed. Now, the lead of dummy's last Spade effects a double squeeze. East must guard Clubs and West must guard Hearts, so neither opponent can guard Diamonds.
Trap: cashing the Ace early would cause a premature commitment from dummy. East would hold the same red suit as the dummy, and the squeeze would evaporate.
