precursor
'der Vorläufer' and 'der Wegbereiter' both have to do with a later development. 'Vorläufer' usually means an earlier form, version, or person that existed before something later. The focus is on the chronological order. 'Wegbereiter' means a person or thing that creates the foundation for something new through ideas or work. Here, the focus is on making something possible. The words can be confused because both come before a development. In practical terms: a 'Vorläufer' is there beforehand; a 'Wegbereiter' clears the way.
