The square honoring Houdini was damaged the night of Halloween 2000, exactly 25 years after the famous magician's star was first unveiled.
The newly restored marker is to be unveiled Friday afternoon courtesy of the Academy of Magical Arts in association with The Magic Castle.
Expected to attend the re-dedication are actor Neil Patrick Harris, illusionists Penn & Teller and Siegfried Fischbacher, actresses JoAnne Worley and Tippi Hedren and Magic Castle co-founder Milt Larsen.
Among those who contributed to the restoration are top magicians such as David Copperfield, Penn & Teller, Lance Burton, Tihany, Marvyn Roy (Mr. Electric,) and Siegfried and Roy.
The Magic Castle, a popular magic club, said it will hold a reception after the unveiling.
Houdini died on Halloween 1926 at age 52.
