1908 Walter Bitterlich was born in Reutte, Austria.
He will invent Variable Plot Sampling, and the Relascope,
(among other things).
His father was a well known and well liked forester from the TIROL
Hunting is his fathers
responsibility, along with forestry - in the valley
holding the imperial hunting lodge.
Walter was descended from several generations of foresters,
and did practical forestry work in the Tyrolean Alps.
(Hunting, Tirol, 1941)
Heads were mounted on his Salzburg home.
• Walter served on the Russian Front, (received an Iron Cross, 1st class) encircled twice (one by Russians, once by the US), was wounded, and sent back to Normandy to “recover” …
• just in time for the D-day invasion.
• Even during these years he was inventing.
He imagined chasing planes with drones
And planting aerial mines
His drone – much like the B2 stealth
A top view of the drone
They are to attack the sound of the plane
Sensor hexagons will locate the sound
Sound location by rings of Hexagons
The war bureaucracy delays – of course
Walter’s hexagons are later applied to trees
Blue trees change size and become an average (red) size,
with average areas around them.
From his book The Relascope Idea
Tenneck 1946 (Father) Zell am See 1949 (Son)
Walter the Athlete, and his son
The Ice Dancer, ages 70-95
At age 95 he could no longer
lie to the potential
partners about his age
(as if he would ever fall …)
Walter Bitterlich: (1953)
The Thinker
who produced “Variable Plot”
or “Angle-Count” Sampling.
I met him in 1970
A fictional account of his life as “Forestmeister
Gibrect”
Walter’s book belittles measuring every tree, which
he had to do.
He wanted to sample.
