Two bold words with a broad looped surname P
Max Planck appears in two dark recognizable groups. A taller curved M opens the first word, while the surname begins with a large upper P loop before smaller rounded connections and a rising finish. Compare those two beginnings with the low body letters: the name’s strongest emphasis shifts toward the surname’s broad opening.
Max Planck signature analysis
Max Planck’s signature sample has 18° of backward slant, a near-level baseline and 3 enclosed loops. Use the layers to follow the writing line, letter band, slant and enclosed loops.

Opening, letter body and finish
The enlarged opening stands above the smaller letters. The opening-to-body ratio is 2.47×, while the whole image is 4.00 times as wide as it is tall. The rightmost ink finishes above the writing line; look at this ending separately from the slant of the letters themselves.
Loops and the lower flourish
The sample contains 3 enclosed loops and 3 main ink groups. The letterforms carry the main horizontal movement; there is no long lower underline detected beneath their band.
Max Planck’s signature in graphology
Traditional graphology associates enlarged capitals with public emphasis. The looped P adds expressiveness midway through the specimen, while the smaller rounded continuation gives the readable words a flowing rhythm.
