Jennifer Blumin

Jennifer Blumin went missing with sons Phineas “Finn” Ramsey, 4, and Theodore “Theo” Ramsey, 3, and boyfriend Nathan Ulrich on May 15, 2017, when the four were flying in a small twin-engine plane from Puerto Rico to Florida. Their bodies were never found but plane debris was found a day later off the coast of the Bahamas. The father of the children, who was in New York at the time of the crash, was the architect James Ramsey. Over the past 13 years, Ms. Blumin, the founder and chief executive of Skylight Group, had become a prominent player in the fashion industry, pioneering the practice of taking short-term leases on large, derelict buildings and renting them to clients like Ralph Lauren and Google for parties and fashion shows. She got her start in the business at Ketchum, the global public relations firm. Ms. Blumin took out a series of loans on Manhattan properties and flipped them. Equal parts developer, event planner and urban archaeologist, she took over 18,000 square feet of abandoned industrial space at Hudson and Spring Streets early on, transforming it in 2004 into a clean white box that was used by clients including Tommy Hilfiger and Nike.
