The description of the physical law by local fields started with classical fields a long time ago, to the delight of physicists and mathematicians alike.
That quantized fields describe the electroweak and strong interactions successfully is a more recent message, and demanded an understanding of the infinities which accompany local interactions.
This renormalization program is only now slowly finding its mathematical identification. We will overview this development, and discuss consequences for the incorporation of gravity into the picture, and the well-being of the notion of fields.
