He accepted the kings offer, and left Celle for Berlin; took possession of the 400 acres; sold it immediately, and bought the present landed estates Moegelin, and obtained all the privileges of a nobleman. It was in June, 1804, that he took possession of Moegelin. The loss of his flocks by rot and the French wars, were great calamities, especially in the commencement of his operations; but he conquered all difficulties by perseverance; and in 1806 the academy was opened. Twenty pupils inscribed their names immediately; the number increased with every year. He distinguished himself in the improvement of wool; his flocks were superior to any in Prussia. His written works increased his fame, and the sovereigns of Russia, Prussia and many others sent him their orders of knighthood. He. purchased additional property for his younger son Albrecht Philipp Thaer, the later proprietor of Moegelin, who was entirely devoted to agricultural pursuits. In the year 1828, he had a severe attack of rheumatism, and his health began to decline; in 1827, his eyesight failed entirely. His sufferings were great, but he bore them with fortitude and resignation, and at last, on 28 October 1828 in Wriezen, death put an end to his pains. Thaer is buried in his garden, opposite the family dwelling, on the shore of a small clear pond, among the trees which he planted himself, "his children," as he called them. His tomb is under the eves of a chapel. No cold, huge block of marble tells you that here lies father Thaer; but above his grave rises a pyramid of flowers which with their fragrance arrest the attention of visitors, and point with their rich colored petals to the grave, where the man lies who loved them, and who spent his life among them, watching their mysterious habits, to catch a glimpse of the Great Mother's secret operations. Over his grave the ornaments of nature's rich temple mourn for their departed friend. His consort lies by his side surrounded by shrubs and trees. Nowadays there is a grave memorial in Möglin in Brandenburg, Germany, see image. Albrecht Thaer was the first Agricultural scientist, who arranged the existing facts and theory of agriculture in a proper system. His works are highly valued among all agriculturists, and in his time referred to as a magazine of solid truths. The Albrecht-Thaer-Schule in Celle was founded by Thaer early 19th century.
