Princess Helena around 1910

Princess Helena of the United Kingdom (25 May 1846 – 9 June 1923) was the fifth child of Queen Victoria and Prince Albert. She was educated by private tutors chosen by her father and his close friend and adviser, Baron Stockmar. Her childhood was spent with her parents, travelling between royal residences in Britain. In 1866 she married the impoverished German Prince Christian of Schleswig-Holstein. She was the most active member of the royal family, carrying out an extensive programme of royal engagements at a time when royalty was not expected to appear often in public. An active patron of charities, she was one of the founding members of the British Red Cross. She was founding president of the Royal School of Needlework, and president of the Workhouse Infirmary Nursing Association. As president of the Royal British Nurses' Association, she was a strong supporter of nurse registration against the advice of Florence Nightingale. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
