It's been a sad few days for motorsport following the passings of Murray Walker and Sabine Schmitz, but F1's fan community was also hit hard on Wednesday with the news that its most impassioned member, Charaf Eddin, had succumbed to cancer.
Charaf became blind around the age of 20, but the unfortunate hardship never dampened his enthusiasm and passion for Formula 1.
A familiar figure in the paddock who had befriended many, Charaf would head out and stand trackside on Grand Prix weekends and instinctively follow the action, having memorized every corner of every track visited by F1.
The emotional highlight of the visually-impaired superfan's experience in F1 came when he was offered - much to his astonishment - the surprise ride of his life onboard F1's two-seater at the Spanish GP at Barcelona in 2018.
Since yesterday, many in F1 have paid tribute to the young Frenchman, including Ferrari's Charles Leclerc who remembered Charaf's passion and perennially happy demeanor.
"Charaf was such an amazing person," wrote the Monegasque on social media. "You always had a huge smile on your face every time we spoke together.
"Always so positive and always using the right words whenever I was feeling down. I’ll miss you, and the whole paddock will miss you. Rest In Peace my friend."
Daniel Ricciardo and Nico Rosberg were also among those who took to social media to recall their friend Charaf.
