She enrolled at the Academia Politécnica do Porto to study civil engineering of public works, which she concluded with various distinctions in 1894. Two years later, she was granted with the "Civil Engineering certificate of capability" to practise as a professional engineer, and although she never did, she was the first formally and fully recognised European female engineer. Lydia Weld was the first woman to graduate in engineering from the Massachusetts Institute of Technology, starting her studies in 1898 and going on to work as a draughtsman in the engineering division of Newport News Shipbuilding and Dry Dock Company. She later became the second woman member of the American Society of Mechanical Engineers. Other women in engineering in the same time period include three Danish women: Agnes Klingberg, Betzy Meyer, and Julie Arenholt, who graduated from 1897 to 1901, at the Polyteknisk Læreanstalt, today known as the Danmarks Tekniske Universitet. Women without formal engineering degrees were also integral to great 19th century civil engineering feats. Emily Warren Roebling is recognized as managing the construction of the Brooklyn Bridge, and was the first person to cross the bridge at its opening ceremony in 1883. Roebling's husband, Washington Roebling, worked as the chief engineer for the Brooklyn Bridge project until he fell ill of decompression sickness. Upon her husband's illness, Emily Warren Roebling assumed her husband's duties at the project site, and taught herself about material properties, cable construction, calculating catenary curves and other subjects. 20th century: entry into engineering programs In the early years of the twentieth century, a few women were admitted to engineering programs, but they were generally looked upon as curiosities by their male counterparts. 1900s On 27 July 1904, Maria Elisabeth Bes graduated in chemical engineering from the Polytechische School te Delft, becoming the first female graduate engineer in the Netherlands. In 1906, Anna Boyksen became the first female engineering student at the Technische Hochschule München in Germany. Nora Stanton Blatch Barney (1883–1971), daughter of Harriot Stanton Blatch and granddaughter of Elizabeth Cady Stanton, was the first woman to receive a degree in civil engineering from Cornell University in 1905. In the same year, she was accepted as a junior member of the American Society of Civil Engineers; however, twelve years later, after having worked as an engineer, architect, and engineering inspector, her request for an upgrade to associate membership was denied. Olive Dennis (1885–1957), who became
