I want to know the answer to the following question:
What was the first modern text book?
All the background I'm provided with is that "Schleiden was a microscopist and an early plant anatomist who co-founded the cell theory with Theodor Schwann and Rudolf Virchow and was among the first to grasp the significance of the cell nucleus that had been described by Robert Brown in 1831.". Is that enough to answer the question?
Answer: no
