Miscellaneous: 65 years ago – The Bayer Cross shines again

Carl Duisberg switched on the Bayer Cross, back then the biggest freestanding illuminated advertising, above the Leverkusen Works for the first time on 20 February 1933. The cross had a diameter of 72 metres and 2,200 light bulbs. Before the Second World War, it hung for the next six years between two chimneys each 126 metres tall.

It was designed as a flashing sign: The circle is initially visible and then the letters in the cross are switched on. The whole thing is repeated after a blackout phase.

The Bayer Cross was switched off at the outbreak of war in 1939 due to the lighting regulations and was then dismantled. For the next 19 years there was darkness over the Works.

The Leverkusen landmark was illuminated again in its current form on 2 September 1958. It is somewhat smaller than its predecessor and does not flash any more. The diameter is now only 51 metres and it has a circumference of 160 metres.

A fan-based campaign to save our landmark was launched n 2007 after Bayer AG wanted to pull it down. Instead the company wanted to project the cross as digital illuminated advertising on the Bayer office tower block. 21,000 people signed up to keep the Bayer Cross where it is. I hope it will continue to shine for a long time.

Birthday boy of the month 1: Harry Gniech turns 75

Harry Gniech was born on 14 October 1951 in Leverkusen-Schlebusch. At the age of six, he joined SV Bayer 04, initially in the athletics section. The boy actually wanted to play football, but was only allowed to switch to the football team when he turned nine. Harry quickly established himself as a playmaker in midfield. Despite his talent, the path from the youth team to the first-team squad was a long one back then. In the 1973–74 season, his former U19 coach, Friedhelm Renno – who was by then in charge of Bayer 04’s first team – selected him for his first match with the professional squad.

From the archives: 60 years ago – The strike

In the first week of October 1966, professional footballers decided to take an unusual step – they went on strike. They felt compelled to resort to this action, which was relatively uncommon until then, to give greater weight to their demands for fair pay. They reasoned that, with three draws, they were entitled to a bonus; at the very least, a points bonus of 75 Deutschmarks that was agreed before the start of the season.
