Both these guys are authors of famous fightbooks from ancient Germany.
Hans Talhoffer- A 15th century judicial duel instructor, martial arts instructor and known mercenary/assassin. Theres records of him being jailed for assasinating a robber-knight among other things. There is also a possibility he was the founder or inspiration for the Marxbrüder fencing guild. Talhoffer is also possibly of the Liechtenauer tradition although thats up for debate. On top of his combat training Talhoffer was a well educated man, who took interest in astrology, mathematics, onomastics, and the auctoritas and the ratio.

Vs
Joachim Meyer - 16th century cutler and member of Freifechter fencing guild , possible ex soldier (according to Roger Norling), served on the town gaurd and last of the Liechtenauer tradition. Meyer was also hired by a duke as master at arms weeks before dying of pneumonia.
Meyer’s system is a little “flashier”/“sportier” than traditional KDF/Liechtenauer/German martial arts and has some Italian influence(Bolognese/di Grassi/Marozzo) in the dagger and sidesword.
