Humboldt State University
Robert A. Paselk Scientific Instrument Museum
In 1921 Humboldt State Normal School was renamed Humboldt State Teachers College and Junior College (Humboldt STC), Homer Arnold (who would become professor of Mathematics and Philosophy and teach Civil Engineering) was hired, and the Administration Building (Founder's Hall) was completed.
The initial catalogs (Circular of Information) for Humboldt STC had no course descriptions for science courses taught at Humboldt. Instead they had an excerpt of the UC Berkeley catalog to show students what was expected and available there. The 192526 Circular first describes a variety of science courses apparently taught at Humboldt. The first two permanent science faculty members, Horace Wheeler and Robert Poultney, were also hired at this time. Humboldt was authorized to offer the B.A. degree in 1927, which probably lead to Humboldt's first acquisition of a significant body of scientific instrumentation. By 1932 HSTC had reached an enrollment of 388, and was offering four A.B. degrees, including one in Biology.
I have chosen to provide extracts from the 192728 Circular. The Humboldt State Teachers College Circular of Information for College Year 192728 listed a Faculty of 23, which included the President, a Dean, the Principle for the training school, an assistant librarian, a librarian/instructor in "recreational reading", the registrar, and a secretary. Of the fifteen primarily teaching faculty, only two were listed as teaching science and mathematics: Horace Wheeler, and Robert Poultney. Homer Arnold, who would be listed as a Professor of Mathematics in the catalog beginning in 1933, was listed as professor of Education from 19211932.
The biographical information on these three individuals are taken from the Circular (pp 8 & 9). The photographs are from the first yearbook for Humboldt, Cabrillo, which was published for a single year, 1927.
One and a quarter pages of "natural science" coursework (pp 723) and one page of mathematics coursework (p 68) appear in the 1927 Circular. OCR versions of these pages are reproduced below.

C. TRIGONOMETRY.
Subject matter: Elementary trigonometry. Prerequisite: High school
algebra and geometry.
Two units, two onehour periods per week.
D. ALGEBRA.
Subject matter: Quadratic equations, exponents and radicals, practice
in the use of logarithms, and theory of equations. This course
is designed particularly for those who wish to extend somewhat
their knowledge of algebraic theory, and for those who desire
proficiency in the technique of algebraic manipulation for the
successful (subsequent) pursuit of coordinate geometry, statistics,
or theory of investment. Prerequisite: One year of high school
algebra.
Two units, two onehour periods per week.
MATHEMATICS 3 and 4. Introductory note:
A knowledge of calculus (and its prerequisites) enables the student
to solve problems concerning variable quantities; precisely as
a knowledge of arithmetic or algebra enables him to solve questions
concerning constant quantities. Students intending to take up
scientific courses should note that calculus is necessary for
the solution of many problems which arise in physics and engineering.
COORDINATE GEOMETRY 31
Subject matter: A review of algebra and trigonometry and an introduction
to Coordinate geometry. Prerequisite: High school algebra and
trigonometry.
Three units, three onehour periods per week.
3B. DIFFERENTIAL CALCULUS.
Subject matter: A continuation of plane coordinate geometry, a
study of differential calculus and an introduction to integral
calculus. Prerequisite: mathematics 3A or equivalent.
Three units, three onehour periods per week.
4A. INTEGRAL CALCULUS.
Subject matter: A review of differential calculus and study of
integral calculus. Prerequisite: Differential calculus
Three units, three onehour periods per week. .
4B. INTEGRAL CALCULUS. (Cont'd.)
Subject matter: Space coordinate geometry, calculus of three variables, infinite series, introduction to differential equations and applications of integral calculus to problems in geometry, physics, and engineering. Prerequisite: Mathematics 4A.
Three units, three onehour periods per week.

1. ELEMENTARY AGRICULTURE
A study of general agricultural problems which students will meet
in teaching in rural communities.
Three units, three onehour periods per week.
BIOLOGY 1A.
Lecture and laboratory courses designed to give to the student
the fundamental principles of biology. Study is made of protoplasm,
the living substance; the cell, the unit of biological structure,
the onecelled organism; the manycelled plants and animals; the
manufacture and utilization of food; growth; waste, elimination
and death of organism.
Three units, two onehour and one twohour periods per week.
BIOLOGY 1B.
This course is a continuation of Biology 1A. It is a lecture and
1 laboratory course including a study of growth and reproduction
in plants and animals, the physical basis of heredity, the laws
of heredity, the evidences and theories of organic evolution,
man's place in nature and biology and human progress.
Three units, two onehour and one twohour periods per week.
101. GENETICS.
Lectures and discussions on the laws of heredity and their relation
to the improvement of plants and animals and the human race. Special
reference will be made to the inheritance of mental traits in
man.
Three units, three onehour periods per week.
102. GENERAL ANTHROPOLOGY
Study of the origin and antiquity of man; man as an animal, races
And race problems and earliest culture and growth of language
and religion
Three units, three onehour periods per week.
1A. GENERAL INORGANIC CHEMISTRY.
Subject matter: The theories and principles underlying modern
chemistry. Prerequisite: High school chemistry.
Five units, three onehour lecture periods and two threehour laboratory periods per week.
1B. GENERAL lNORGANIC CHEMISTRY (continued).
Subject matter: The qualitative properties of the several elements and their compounds; the chemistry of various industrial processes and commercial preparations. Prerequisite: Chemistry 1A.
Five units, three onehour lecture periods
and two threehour laboratory periods per week.
