The state of academic life at the Ljubljana Lyceum was regrettable at that time. The professors limited themselves, as was usually the case at other lyceums at that time, to reading from their notebooks, to give explanations in their lectures, and if, in spite of this, an ambitious talent did emerge in exceptional circumstances, this was truly only due to a vital drive for knowledge breaking through despite all obstacles. Then the brilliant Schulz came to Ljubljana bringing with him a hitherto unknown excitement and ambition among the young students. His inaugural speech made a moving impression. With awe-inspiring power and captivating eloquence he described the whole life of a high school student and in particular the sublime importance of the true study of the mathematical discipline. Filled with a fiery love of science, he knew superbly how to instil the spiritual delight of scientific endeavour in his listeners with warmth and emotion. In a humorous way, delivered with a deep philosophical eye, he turned this subject into a true gymnastics of the mind and the theories developed into a self-acquired, inalienable possession of his students. ... He gave lectures on higher mathematics to those with talent. Schulz ... was always eager to present in its best light the practical importance of mathematics in its many-sided applications to all branches of knowledge. This was demonstrated by the practical measurements that he carried out with his students every year in the summer months and which were a real celebration of joy for them; he showed this through his lectures on popular astronomy, which were as comprehensible as they were witty and which were attended by a large audience from all classes of the population. His all-round beneficial activity, his extensive knowledge, his cheerful, friendly and honest character won him the love of the young students as quickly as the respect and trust of the entire population. Schulz was the invigorating focal point around which all people of science and art gathered. Everyone sought his friendship and his witty, instructive company.

The higher mathematics was taught at the university for the first time by Leopold Schulz von Straschnizki. He was one of the best Austrian mathematicians of those times. In 1835 two of his students defended dissertations in pure mathematics. In 1838 L Schulz obtained a chair in Vienna Polytechnic, which was a considerable loss for the University of Lwów.

Through his writing he sought to raise and stimulate interest in mathematics: for example, in his "Handbook of Special and General Arithmetic for Practitioners" he made many of the treasures of science, which had previously only been accessible with the help of infinitesimal calculus, accessible to a wider public by carrying out many proofs using elementary methods. This work was often associated with extraordinary difficulties and expenditure of time and brought him far less fame than the successful results of research investigations, but for this work those involved in practical work had to be particularly grateful to him. In the same spirit, Schulz offered to hold popular lectures on geometry and arithmetic for artists and craftsmen on Sundays and holidays "free of charge", and the government accepted this request. Even in these lectures, Schulz's great teaching ability and the practical tact that always and everywhere distinguished him in his profession were preserved. In addition to these lectures on the elements of arithmetic and geometry, which were attended by the largest audience and had the most beneficial effects for the industrial classes, he also gave lectures on the use of the English slide rule, which he was the first to draw attention to in Austria and Germany and which he endeavoured to introduce especially in the handicrafts sector. On his instructions, this instrument was made by a Viennese mechanic, and his instructions for its use were then published by Rohrmann in 1843. He himself invented a slide rule, an instrument that is very suitable for all kinds of construction calculations and was published under the title: "Professor Schulz von Straßnitzki's slide rule, published by Anton Schefzik" (1845).

We now see the dawn of Germany's freedom and greatness; what we longed for in our youth, what we only imagined in bold images, is now nearing fulfilment; but many struggles and persevering strength are still needed before the bright day breaks; we older people will not live to see it; we will only see the promised land like Moses, without entering it. But the hope that the honest, intelligent, great German people will no longer be torn apart, no longer enslaved, no longer mocked by even the smallest of neighbours - but that it will be powerful, strong, and will take the place worthy of its intelligence among the peoples of Europe - this hope inspires us, and this hope is based primarily on our brave German youth, who are so passionate about freedom and order, justice and truth, who are actively working on the building of the future and who will protect the palladium of social order with a firm hand. The present anxious times are only the birth pangs of the coming great time, which will blossom not for us, but for our children and grandchildren.
