De Vries, who recently flew to space on a rocket launched by Bezos’ aerospace company Blue Origin, was identified as one of two victims killed in the New Jersey crash, State Police previously confirmed to PEOPLE. Thomas P. Fischer, 54, was also killed during the incident.
On Friday, Bezos spoke out about the tragedy on social media, calling the 49-year-old “a visionary, an innovator [and] a true leader.”
“Such a tragic loss,” Bezos, 57, wrote on Instagram beside a photo of de Vries smiling next to a model Blue Origin rocket. “Warm and full of life, Glen made us laugh and lit up the room.”
“Lauren and I are heartbroken and will remember the precious time we got to spend together,” the Amazon founder continued. “Our deepest sympathies are with his partner, Leah, and all his loved ones. The world lost you too soon, Glen.”
Bezos’ partner, Lauren Sánchez, also expressed her sadness in a touching post on social media.
“Such a painful loss today. We got to know Glen de Vries, an incredible man, and his partner Leah last month,” she wrote. “Leah’s love for Glen was visible every time we saw them together.”
“When he took off for space she gripped my hand so tight it hurt. Thinking of that moment today with a broken heart,” Sánchez, 51, continued. “Our deepest sympathies go out to Leah and Glen’s family, we are so saddened by the tragic news.”
In a statement, Blue Origin wrote: “We are devastated to hear of the sudden passing of Glen de Vries. He brought so much life and energy to the entire Blue Origin team and to his fellow crewmates. His passion for aviation, his charitable work, and his dedication to his craft will long be revered and admired.”
De Vries was one of four crew members aboard the New Shepard rocket that blasted into space for the NS-18 mission last month.
It had been a memorable moment for de Vries, who previously said that going into space was his “oldest, and lifelong enduring, dream” in a social media post.
In addition to his interests in aviation and space, de Vries was also a trustee for his alma mater, Carnegie Melon University, and the co-founder of Medidata Solutions, a tech company that develops software as a service, per their website.
