Leonhard Baldner

Leonhard Baldner is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Leonhard Baldner rather than just read about it. In short: Leonhard Baldner or Leonard Baltner (1612 – 1 February 1694) was a Strasbourg fisherman and naturalist who produced a hand-written illustrated book on the fishes, birds, and mammals titled Vogel-, Fisch- und Thierbuch. Only six manuscript copies are now known to exist, two are dated 1653 and the other four 1666.

Key takeaways

  • Leonhard Baldner belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Leonhard Baldner to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Leonhard Baldner from memory before moving on to harder problems.

Reference excerpt

Leonhard Baldner or Leonard Baltner (1612 – 1 February 1694) was a Strasbourg fisherman and naturalist who produced a hand-written illustrated book on the fishes, birds, and mammals titled Vogel-, Fisch- und Thierbuch. Only six manuscript copies are now known to exist, two are dated 1653 and the other four 1666. He was one of the early pioneers to use glass aquariums to study fish in life. He was also possibly the first to write on the migration and life-history of the salmon.

Biography The exact date of birth of Baldner is unknown but he was born in an old fisher family in Strasbourg. He married Salome, daughter of Hans Michael Fries on January 25, 1636, and had four children. He married his second wife Anna Ursula, daughter of a goldsmith, Abraham Sprengel in 1650 and they had four children. He worked as a toll collector, later a forester and then a forest manager. After the death of his second wife, he married Barbara, daughter of Benedictus Grossen, a professor of Hebrew. They too had four children of whom the youngest son, Andreas born in February 1673 transcribed the manuscripts of his father. Baldner died on February 1, 1694 and is buried in the Saint-Urbain cemetery in Strasbourg.

The bird, fish, and animal book (1666) The original manuscript drawn and written by the artist was inherited by Baldner's youngest son who had it until 1687. It was then purchased by organ builder Silbermann who donated it to the city of Strasbourg. The copy was destroyed on the night of August 24, 1870, during a siege by the Prussians. A facsimile edition of Baldner's manuscript was published by Robert Lauterborn in 1903 although there are slight differences between the plates among the various surviving manuscript editions. It included three parts; the first on birds included 68 species while the second dealt with 45 fishes and crustaceans. The third part included quadrupeds and other animals. His writings were based on personal observation and he did not rely on reports by others. He hired a Strasbourg artist, Johann Georg Walther, to illustrate the book. At least one and probably two copies of the book were obtained by Francis Willughby in 1663. The German text was translated into English for Willughby and his collaborator John Ray by Frederick Slare.

Worked examples

Example 1 — a first encounter with Leonhard Baldner

Start with the simplest possible case. Write down what Leonhard Baldner claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Leonhard Baldner before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Leonhard Baldner ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Leonhard Baldner

In research
Leonhard Baldner appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Leonhard Baldner in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Leonhard Baldner is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1612 births, 1694 deaths, 17th-century German naturalists, so understanding it makes those chapters shorter.
In everyday life
Look for Leonhard Baldner outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
