Nov 16 at 8:08 comment added Manfred Weis @P.R. that had already been noticed in the comments of Gerard Duchamp that was Kurrent and not Sütterlin
Nov 15 at 18:14 comment added P.R. I am aware that all these comments are very old, but I just want to add that wikipedia puts the invention of Sütterlin to 1911. So it was invented after the first publications mentioned in other answers above. (wikipedia says now: "Graphic artist Ludwig Sütterlin was commissioned by the Prussian Ministry of Science, Art and Culture (Preußisches Ministerium für Wissenschaft, Kunst und Volksbildung) to create a modern handwriting script in 1911.")

Aug 17, 2017 at 8:06 comment added Manfred Weis @DuchampGérardH.E. if your father also changed the order of the loops, then probably also for reasons of speed or because the official way is too awkward. A similar effect can be observed when people try to write the '&' or the '@' sign; I've seen the most adventurous creations.

Aug 17, 2017 at 7:59 comment added Duchamp Gérard H. E. @ManfredWeis Thank you. In fact my father was a perfect German speaker and writer but, maybe, his gothic handwriting, coming from family tradition, was mixed. It looked like Weierstrass p only when the letter was isolated, when not (ligature with the preceding letter) it showed an upgoing ligature indicating that he was writing the bottom loop first.
Aug 17, 2017 at 6:38 comment added Manfred Weis Or someone not familiar with Kurrent mixed up the order of the loops, thus 'inventing' the $\wp$
Aug 17, 2017 at 6:30 comment added Manfred Weis If one looks at a Kurrent alphabet from 1865, one sees, that the small letter $p$ is written with two loops, the top one first and then the bottom one. It might be that Weierstrass switched that order (maybe because that allowed faster writing).
Aug 17, 2017 at 6:20 comment added Manfred Weis @DuchampGérardH.E. in Kurrent writing of the capital letter P starts from upper left and there is no inflection point before entering the loop; the capital letter K however starts from the right and has an inflection point before the loop. This isn't meant to rule out the explanation that the origin of $\wp$ is Kurrent - it only is meant to indicate that questions still remain. What is desparately missing is a handwritten text from Weierstrass himself.
Aug 17, 2017 at 3:15 comment added Duchamp Gérard H. E. @teikakazura No, not Sütterlin but Kurrent (I saw it in my father's handwriting when a child).
Aug 15, 2017 at 4:25 comment added teika kazura Though similarity is a subjective matter, I'm afraid the $\wp$ letter doesn't look to me like Sütterlin. However I found an example of Sütterlin-like lowercase p (but published in Paris in French!) Search for "Sütterlin" in my edited question.
