Lauda had a series of health-related problems over the last number of months, undergoing a lung transplant operation in August of 2018.
The Austrian won three Formula 1 world championships during his career which ended in 1985, however he remained a strong presence in the paddock after he concluded his driving career.
In September of 2012, Lauda was appointed to the role of non-executive chairman of Mercedes AMG Petronas Motorsport, and was instrumental in bringing Hamilton from McLaren to Mercedes for the 2013 season.
"I will miss our conversations, our laughs, the big hugs after winning races together,” Hamilton wrote in a post shared across his social media platforms.
“It’s truly been an honour working alongside you over these past 7 years. I wouldn’t have even been in this team if it wasn’t for you.
“God rest your soul. Thank you for being a bright light in my life. I’ll always be here for your family should they ever need me.
“Love you man. Your friend always, Lewis.”
I’m struggling to believe you are gone. I will miss our conversations, our laughs, the big hugs after winning races together. God rest your soul. Thank you for being a bright light in my life. I’ll always be here for your family should they ever need me. Love you man pic.twitter.com/cotUpuvW2F— Lewis Hamilton (@LewisHamilton) May 21, 2019
