Those increases offset a 20% drop in Air Lease Corp. stock as the company weathered the grounding of the Boeing 737 MAX aircraft before being hit by the Covid-19 pandemic that has devastated the travel industry. Udvar-Házy put his 28,600-square-foot Beverly Park estate, dubbed Villa Firenze, on the market in 2018 for $165 million. The property remains unsold. He owns two Gulfstream jets, which together are valued at roughly $80 million. Udvar-Házy’s art collection saw a modest increase in value over the past year.THE BUZZ: Aircraft leasing pioneer Udvar-Házy founded International Lease Finance Corp. in 1973. He sold the company to American International Group in 1990 for $1.3 billion, staying on as chairman and chief executive until 2010. Udvar-Házy then launched Air Lease where he’s now executive chairman. Air Lease has helped financially squeezed airlines restructure their fleets by leasing them newer, more fuel-efficient planes. The company has plenty of cash reserves but must navigate poor market conditions for at least another year. Udvar-Házy was born in Budapest, Hungary, and moved to the United States with his family in 1958, fleeing Soviet occupation. He graduated from UCLA with a bachelor’s degree in economics and holds an honorary doctorate from Embry-Riddle Aeronautical University. In 1999, Udvar-Házy donated $60 million to the National Air and Space Museum, which named its Northern Virginia facility after him. The campus houses NASA’s Space Shuttle Discovery and Lockheed Corp.’s SR-71 Blackbird. Udvar-Házy and wife Christine have donated more than $100 million to Stanford University and Embry-Riddle Aeronautical University in Prescott, Ariz. He was honored with the Grand Cross of the Order of Merit of Hungary in 2016.
