我初次认识维廉同志是在1937年冬天,他随欧亚航空公司到达昆明之时。当年,抗日救亡歌咏运动正在昆明蓬勃兴起,民众歌咏团、歌咏骨干训练班吸引着千百个青年。维廉同志一到达昆明,立即投身于歌咏运动,成为其中最活跃的组织者之一。那时,他22岁,由于他知识广博、为人持重,大家都尊称他为曹老师。 My first acquaintance with Comrade Wilhelm was in the winter of 1937, when he arrived in Kunming with Eurasian Airlines. That year, the anti-Japanese national salvation movement is flourishing in Kunming, and the popular singing groups and song-winning backbone training classes have attracted thousands of young people. As soon as Comrade Wilhelm arrived in Kunming, he immediately joined the singing movement and became one of the most active organizers. At that time, he was 22 years old. Due to his extensive knowledge and heavy personal responsibility, everyone honored him as Cao.
