Jakob Johann von Uexküll (September 8, 1864 -
July 25, 1944) was a Baltic
German biologist who had important achievements in the fields of muscular physiology
and the cybernetics of
According to Giorgio Agamben, von Uexküll had been a Baron before his family lost most of their fortune in World War I, although

There, von Uexküll became interested in how living beings subjectively perceive their environment(s). Picture, for example, a meadow as seen through the compound eyes of a fly, continually flying through the air, and then as seen in black and white by a dog (with its highly efficient sense of smell), and then again from the point of view of a human or a blind tick. Furthermore, think of what time means to each of these different beings with their relative lifespans. Von Uexküll called these subjective spatio-temporal worlds "Umwelt". These Umwelts are distinctive from what von Uexküll termed the "Umgebung" which would be objective reality were such a reality to exist. Each being perceives its own Umwelt to be the objective Umgebung, but this is merely perceptual bias.
Von Uexküll's writings show a specific interest in the various worlds that exist ('conceptually') from the point of view of the Umwelt of different creatures such as ticks, sea urchins, amoebae, jellyfish and sea worms. This gives some of his writings a poetical quality.
The biosemiotic turn in Von Uexküll's analysis occurs in his discussion of the animal's relationship with its environment. The Umwelt is for him an environment-world which is (according to Agamben), "constituted by a more or less broad series of elements [called] "carriers of significance" or "marks" which are the only things that interest the animal." Agamben goes on to paraphrase one example from Von Uexküll's discussion of a tick, saying,
"...this eyeless animal finds the way to her watchpoint [at the top of a tall blade of grass] with the help of only its skin’s general sensitivity to light. The approach of her prey becomes apparent to this blind and deaf bandit only through her sense of smell. The odor of butyric acid, which emanates from the sebaceous follicles of all mammals, works on the tick as a signal that causes her to abandon her post (on top of the blade of grass/bush) and fall blindly downward toward her prey. If she is fortunate enough to fall on something warm (which she perceives by means of an organ sensible to a precise temperature) then she has attained her prey, the warm-blooded animal, and thereafter needs only the help of her sense of touch to find the least hairy spot possible and embed herself up to her head in the cutaneous tissue of her prey. She can now slowly suck up a stream of warm blood."
Thus, for the tick, the Umwelt is reduced to only three (biosemiotic) carriers of significance: (1) The odor of butyric acid, which emanates from the sebaceous follicles of all mammals, (2) The temperature of 37 degrees celsius (corresponding to the blood of all mammals), (3) The (hairy typology of mammals).
Works by scholars such as Kalevi Kull connect von Uexküll's studies with some areas of philosophy such as phenomenology and hermeneutics. Von Uexküll is also considered a pioneer of semiotic biology, or biosemiotics. However despite his influence (on the work of philosophers Martin Heidegger, Maurice Merleau-Ponty, Gilles Deleuze and Félix Guattari (in their A Thousand Plateaus), for example) he is still not widely known, and his books are mostly out of print in German and in English, although a paperback French translation of Streifzüge durch die Umwelten von Tieren und Menschen [A stroll through the Umwelten of animals and humans] is currently in print.
His grandson is Jakob von Uexkull.
