Slavoljub Eduard Penkala (Croatian pronunciation: [slâu:b duard pk?:la]) (20 April 1871 - 5 February 1922) was a Croatian engineer and inventor of Dutch-Polish-Jewish descent.[1][2]

"Penkala-Moster" pen and pencil company in Zagreb

Eduard Penkala was born in Liptószentmiklós (now Liptovský Mikulá?), then part of Austria-Hungary, to Franciszek P?ka?a, who was of Polish heritage, and Maria P?ka?a (née Hannel), who was of Dutch descent. He attended the University of Vienna and Royal Saxon Polytechnic Institute, graduating from the latter on March 25, 1898, and going on to earn a doctorate in organic chemistry. During his studies, he attended violin lessons where he met his future wife, pianist Emily Stoffregen. He then moved with his wife to Zagreb (which was then in the Kingdom of Croatia-Slavonia). To mark his loyalty to his new homeland, he took on the Croatian name Slavoljub (the equivalent of slavophile), becoming a naturalized Croat.

He became renowned for further development of the mechanical pencil (1906)[3] - then called an "automatic pencil" - and the first solid-ink fountain pen (1907).[4] Collaborating with an entrepreneur by the name of Edmund Moster, he started the Penkala-Moster Company and built a pen-and-pencil factory that was one of the biggest in the world at the time. The company, now called TOZ Penkala, still exists today.

He also constructed the first Croatian aircraft to fly in the country, the Penkala 1910 Biplane, flown by Dragutin Novak, who was also the first Croatian pilot. He constructed and invented many other products and devices, and held a total of 80 patents.

Among his patented inventions were:

He also founded another company called the Elevator Chemical Manufacturing Company, which produced various chemicals such as detergents, sealing wax, and "Radium Vinovica", a patent-medicine - like product that was billed as curing rheumatism.

He had four children with his wife, Emily.

Penkala died in Zagreb at the age of 50, after catching pneumonia on a business trip. He was buried at the Mirogoj Cemetery.[5]
