Inventions: mechanical principles, flying machines, parachute, water transport, fresco painting technique
Leonardo da Vinci is well-known for his many art works, which count among the greatest of all the Renaissance artists. Along with inventing and applying mathematical principles to art, such as parallax and natural fall of textiles, he made detailed drawings of plants, animals and human anatomy, and discovered hardening of the arteries as a cause of death.
In engineering he was engaged to design original defensive structures and weapons of war. He is credited with designing the first tank, parachute, hang-glider, helicopter, underwater breathing equipment, the double hull, and many mechanical engineering devices, such as swinging bridges, water screws, and a giant arbelesque (crossbow).

Gro Harlem Brundtland, born 1939, is one of the most important figureheads and leaders of the environmental movement. In 1987, she chaired the famous Brundtland Commission for the UNO, which established Sustainable Development as a central goal of development and environmental protection.
This we know: the earth does not belong to man: man belongs to the earth... Whatever befalls the earth, befalls the sons of the earth. Man did not weave the web of life: he is merely a strand in it. Whatever he does to the web, he does to himself.
