The Landis family rose to prominence in real estate development under the leadership of Alan B. Landis (1942-2018), founder and chairman of The Landis Group. Born on October 17, 1942, in New Brunswick, New Jersey, Alan earned a B.S. in accounting from New York University after attending the Hun School of Princeton. He was married to Linda Landis for 45 years; their children are son Scott Landis (wife: Amy) and daughter Dana Landis Birnbaum (husband: Eric Birnbaum), with seven grandchildren: Matthew, Chloe, Charlotte, Annabelle, Emma, Ava, and Max. Alan's siblings included Mark, Diana, Ilene, Tef, and Micky; his parents were Morris and Raye Landis. The family resided in areas including Princeton, New Jersey, and West Palm Beach, Florida, owning property on Davis Island.

As minority investors in the Minnesota Vikings alongside the Wilf family, Alan joined as an original minority ownership partner in the 2005 acquisition of the team. He contributed actively to franchise growth, including the development of U.S. Bank Stadium and the Twin Cities Orthopedics Performance Center in Eagan, Minnesota. Alan's business portfolio featured award-winning projects such as the 560-acre Carnegie Center in Princeton, New Jersey (recipient of the 1991 Urban Land Institute Award for Excellence), Princeton MarketFair Mall, Tower Center Office and Hotel Complex in East Brunswick, New Jersey, and developments in New York City and Connecticut. He also held minority stakes in the New Jersey Nets (key in establishing the YES Network), New York Yankees, New Jersey Devils, and Barclays Center, while serving on the board of directors for Boston Properties.

The family engaged in philanthropy focused on child abuse prevention (National Prevent Child Abuse Organization), blindness research (Foundation Fighting Blindness, Humanitarian Award recipient), Israel Bonds, and education (Landis Family Fine Arts Center at Hun School). No controversies, legal issues, or investigations involving the Landis family were identified in available records. Their influence spans real estate, sports ownership, and charitable causes primarily in the Northeastern United States.
