I worked at w+k London for about 4 years. This is a collection of tributes by people I know. Storing them here for myself but I thought you might enjoy them. Trigger warning some of them are on LinkedIn.
Simon McCrudden, former Planner in w+k London
He tells a tale about the Nokia pitch "On Saturday afternoon Dan sat in silence staring at me as I presented him my terrible strategy."
Iain Tait, ECD in w+k Portland and London
"His brilliance was precisely because he was an introvert, not in spite of it." Dan. The quiet titan.
Michael Russoff, creative director working at w+k London during the Guardian and Honda days.
"I never met Dan. I was in rooms where he was. But I never met/met him."
Michael Wolff, designer and founder of Wolff Olins. It's on FaceBook so I'm not sure if you can read this.
"Like Bill Bernbach who, in his leadership of Doyle Dane Berbach, transformed advertising in his day, Dan Weiden took the baton and, with Wieden and Kennedy, continued to lead."
"If you talk to anyone who has passed through a W+K office, you will likely hear mention of the network’s commitment to the ‘work’ coming above all else."
