This week Richard Lewis, founder of Riversdown House, celebrated his 96th birthday with family, friends, teachers and students.  On a warm summer’s evening, the party sipped champagne as they listened to live jazz music in Riversdown’s beautiful garden.  Richard Lewis was joined by Kai Hammerich, his co-author on their bestselling book Fish Can’t See Water: How national culture can make or break your corporate strategy.  Kai made a moving speech in honour of his friend.  The group then enjoyed a three course dinner, with birthday cake, in the legendary Riversdown dining room.
