(CNN) -- A high school principal has died after going to the hospital to donate bone marrow to try to save the life of a 14-year-old in France.Derrick Nelson, principal of Westfield High School in New Jersey, died unexpectedly Sunday night, according to school officials. His fiancée, Sheronda Braker, said that Nelson suffered complications after his bone marrow donation.The school's newspaper reported in February that Nelson decided to donate his bone marrow to a boy in France after being contacted by Be the Match. The national bone marrow donor program told him that his blood might be a match."If it's just a little bit of pain for a little bit of time that can give someone years of joy, it's all worth it," Nelson told the paper then.In a statement to CNN, Braker said Nelson "was a tremendous father to our beloved daughter Morgan and the best companion and life partner I could have ever asked for.""He loved his family almost beyond belief. He was a man who carried himself with dignity, courage and compassion," she continued. "His last kind and generous act on this earth in giving so someone else might live is a true testament to who he was and how he should always be remembered. We will always love him."in a letter to parents, Westfield Public Schools Superintendent Margaret Dolan said, "Dr. Nelson touched us all with his kindness, compassion, integrity, and endlessly positive attitude. "We hold him and his family in our hearts as we grieve this loss together and I know you join me in granting his family the privacy they have requested."Nelson, 44, served in the US Army Reserve for more than 20 years, according to Dolan. He joined Westfield Public Schools in 2010 as the assistant principal of Roosevelt Intermediate School.He later was assistant principal and principal of Westfield High, which has more than 1,800 students.People praised Nelson as a committed educator and a role model with a strong moral compass.His friend Salim Sivaad, also known as Wayne Clemmons, an Atlanta-based musician, told CNN he received news of Nelson's death from a mutual friend."Derrick was my brother's college roommate and fraternity brother, and that's how I met him back in 1995," he said. "I had not been in contact with him recently. That's why it was such a shock. ... I didn't know he was donating or had the complications before he passed."Jackson O'Brien, senior class president at Westfield High, told CNN affiliate WABC, "He always tried to inspire students in the classroom and outside to be good people. And I think he served as a great role model."Westfield Mayor Shelley Brindle said on Facebook that her family was "devastated" to hear the news."This is a tremendous loss for our community, and I know that our children, and we as parents, will struggle with coming to terms with this over the coming days and weeks," she said. "He was a man of immense character and kindness, and his legacy will live on in the generations of students whose lives he touched."New Jersey Gov. Phil Murphy called the principal's final act "one of selflessness." 3081

"Curiosity. InSight. Spirit. Opportunity. If you think about it, all of these names of past Mars rovers are qualities we possess as humans. We are always curious, and seek opportunity. We have the spirit and insight to explore the Moon, Mars, and beyond. But, if rovers are to be the qualities of us as a race, we missed the most important thing. Perseverance. We as humans evolved as creatures who could learn to adapt to any situation, no matter how harsh. We are a species of explorers, and we will meet many setbacks on the way to Mars. However, we can persevere. We, not as a nation but as humans, will not give up. The human race will always persevere into the future." 683

??Just a little alert to the world: the sky randomly turned dark today in S?o Paulo, and meteorologists believe it’s smoke from the fires burning *thousands* of kilometers away, in Rond?nia or Paraguay. Imagine how much has to be burning to create that much smoke(!). SOS?? pic.twitter.com/P1DrCzQO6x— Shannon Sims (@shannongsims) August 20, 2019 358
