Timeline question[edit]

I'm reading this article and the timeline around 1957/1958 seems a bit mixed up. I am not the subject matter expert and therefore raise this question here in talk instead of amending the article directly. Please understand my genuine intention of achieving clarity and not of debate.

The article says Wichterle had to leave after a political purge in 1958, but then goes onto referring to the Prague symposium in 1957 convincing the state leadership that such research was needed and thus CSAS came into being in 1958. Perhaps these years are somehow correct but it seems that a purge occuring in 1958 and simultaneously establishing a centre in 1958 seem to be contradictory, however perhaps I'm missing something and can be enlightened.

In 1957 Wichterle produced around 100 soft lenses from closed polystyrene molds but the edges split and tore as the lenses were removed. In addition, they required hand finishing. He was determined to find a better way. Unfortunately, Wichterle and other prominent teachers had to leave the Institute of Chemical Technology after a political purge staged by its Communist leadership in 1958. Research into contact eye lenses at the Institute of Chemical Technology came to an end. The International Symposium on Macromolecular Chemistry held in Prague in 1957 convinced the state leadership of the need to establish a centre for research into synthetic polymers. The Institute of Macromolecular Chemistry of the Czechoslovak Academy of Sciences (CSAS) came into being in 1958
