Я сделал как мог, получилось следущее:

He was an industrialist but managed to remain an idealist.
He was cheerful in company but he was sad in private.
He was a lover of all mankind but he never had a wife or family to love him.
He was a patriotic son of his native land but he died alone in the foreign country.
He invented a new explosive dynamite, to improve the peaceful industries, but saw it used as a weapon to kill people.
He was world–famous for his works but he was never personally well-known: while he lived - avoided publicity.
He was a swede but lived for more than 20 years in Russia.
He had never been to school or University but was a skilful chemist and excellent linguist.
He was a man the imaginative, but he had better luck in business and showed more financial sense.

Мне сказали чепухи напорол. Помогите пожалуйста, и ещё вопрос, если у меня каждое предложение начинается с He was это как и в русском языке является ошибкой?
