 Has anyone ever signed an official document "on behalf" (so to speak) of their partner using the skill mentioned in  above?
 When and how did your own signature originate, develop, or change over time (if it ever did)?
Used to be able to duplicate, and regularly did, my late husband's signature on legal documents - always with his knowledge, of course!
Females change their names on average more often than males, so we get opportunities to change our signatures. My first was a flowery copperplate first-middleinitial-surname and I was tired of that by the time I married, which then became a bare-minimum initial-surname cursive scrawl. Then I married and acquired two identical initials, which meant a radical change to a backhanded squiggle which I still have.
There was a time when I signed paycheques, some to myself. Since I got the job before the husband, the cheque signature was completely different from the recipient endorsement. Used to occasionally cause some grief at the bank when I forgot which hat I was wearing!
