Overview
- A new authorized biography draws on Wolfgang Grupp’s long-kept diaries to report that he recorded a suicide attempt, presenting the account in his own words.
- After handing day-to-day control to his children in early 2024, the longtime Trigema leader describes an age-related depression and a personal crisis.
- He dropped his one-heir rule and named both children as co-leaders because both chose to stay at the company and to prevent a sole-heir tax hit that could have drained cash.
- The family says future interviews will cover business only, and Trigema’s IT now uses an in-house AI tool to flag remarks that could be seen as too harsh.
- The book outlines Grupp’s money principles, including avoiding debt, keeping distance from banks, and tightly controlling spending to protect the firm’s independence.
