Why did Conrad Gessner invent the pencil?

Conrad Gessner did not invent the pencil; rather, he contributed to the understanding of natural history and the classification of plants and animals in the 16th century. The modern pencil, as we know it, was developed later, primarily through the discovery of graphite in Borrowdale, England, in the 1560s. The first true pencils were made by encasing graphite in wood, which occurred after Gessner's time. Thus, while Gessner was influential in various fields, he was not the inventor of the pencil.
