"The work of Heinz Heitmann made an important contribution to Bayer 04 being an established and successful member of the Bundesliga family. We are grateful for his decades of commitment and his close association with the club," said Fernando Carro, Bayer 04 CEO.
Heitmann started working in Leverkusen in 1976 as the youth director and manager at Bayer 04. Shortly after that, he became the managing director of the overall club SV Bayer 04 with its football, boxing, fist ball, and ball and athletics sections. And in 1979, the year of promotion to the Bundesliga, Heitmann took over the post of head and director of the football section at the request of the then president Dr. Jürgen Schwericke.
In Bayer 04's first five years in the Bundesliga, Heinz Heitmann was the general manager responsible for almost everything at the club: Finance and budget planning, contract and transfer negotiations, licensing, stadium administration, pitchside advertising, training camps and much more besides. A man for all seasons who played a big part in the increasing professionalisation of the club structures in the first years in the Bundesliga.
When he ended his time as general manager in 1984, Heitmann carried on working in the Bayer works. Of course, he remained attached to football and Bayer 04. In 1992, he took over the voluntary role of managing the club's Veterans team, which was mainly made up from the promotion side of 1979. "Our work together lasted through the decades and they all remained Bayer lads," Heitmann once said. He led the Veterans team up to 2006 before handing over the reins to Michael Kentschke.
A regular visited to the stands at the BayArena and holder of an honorary season card, Heinz Heitmann watched Werkself home games until recently. He passed away in the night from Wednesday to Thursday at the age of 82.

He knows the dressing room, the pitch and the club. But, above all, he knows the feeling of playing for the Werkself at the BayArena: Moussa Diaby is back in Leverkusen after three years. The lightning-fast winger has signed a contract with Bayer 04 until 2031 and he will once again wear the number 19 jersey. The left-footed player previously played for the club from 2019 to 2023, having arrived in the Rhineland from his native France as a promising young talent and eventually leaving the club – having established himself as one of the Bundesliga’s best attackers – to join Aston Villa in the Premier League. Now he has returned to Bayer 04 from Al-Ittihad FC in Saudi Arabia.
