February 5, 1855, Østergård, Hjerm Parish, Jutland (now Struer, Midtjylland), Denmark.
October 9, 1931, Tyler, Minnesota.
Danebod Lutheran Cemetery, Tyler, Minnesota.
Ostergaard was a pioneer among Danish-American pastors and folk school leaders.
He taught at the Elkhorn Folk School, Elkhorn, Iowa, from its beginning in 1878, and helped establish the Ashland Folk School at Grant, Michigan, in 1882.
In 1885 he returned to Denmark, where he founded Stovring Folk School in Stovring, Jutland (which still exists today), but because of his liberal political views a reactionary government refused him financial support.
Soon after this his wife died, leaving him with six children, and his own health impaired. It was during these trying times that he wrote Den Sag er aldrig i Verden tabt.
In 1892, Ostergaard returned to America and, after a period of seminary study, was ordained a Lutheran pastor in 1893. He served a number of congregations in the American Midwest before retiring in 1916 at Tyler, Minnesota, to devote all his time to writing.
Ostergaard wrote a number of novels depicting the life among Danish immigrants, and wrote many songs, an anthology of which was published in 1912 as Songs of the Prairie.
