named after royalty: Princess and Duchess being popular names, as well as Balmoral and Windsor. In June 1889, an African American man named William H. Richardson patented his idea of the first reversible stroller. The bassinet was designed so it could face out or in towards the parent. He also made structural changes to the carriage. Until then the axle did not allow each wheel to move separately. Richardson's design allowed this, which increased maneuverability of the carriages. As the 1920s began, prams were now available to all families and were becoming safer, with larger wheels, brakes, deeper prams, and lower, sturdier frames. In 1965, Owen Maclaren, an aeronautical engineer, worked on complaints his daughter made about travelling from England to America with her heavy pram. Using his knowledge of aeroplanes, Maclaren designed a stroller with an aluminium frame and created the first true umbrella stroller. He then went on to found Maclaren, which manufactured and sold his new design. The design took off and soon "strollers" were easier to transport and used everywhere. In the 1970s, however, the trend was more towards a more basic version, not fully sprung, and with a detachable body known as a "carrycot". Now, prams are very rarely used, being large and expensive when compared with "buggies" (see below). One of the longer lived and better known brands in the UK is Silver Cross, first manufactured in Hunslet, Leeds, in 1877, and later Guiseley from 1936 until 2002 when the factory closed. Silver Cross was then bought by the toy company David Halsall and Sons who relocated the head office to Skipton and expanded into a range of new, modern baby products including pushchairs and "travel systems". They continue to sell the traditional Silver Cross coach prams which are manufactured at a factory in Bingley in Yorkshire. Since the 1980s, the stroller industry has developed with new features, safer construction and more accessories. Prams Larger and heavier prams, or perambulators, had been used since their introduction in the Victorian era; prams were also used for infants, often sitting up. The term carrycot became more common in the UK after the introduction of lighter units with detachable baby carriers in the 1970s. As they developed through the years suspension was added, making the ride smoother for both the baby and the person pushing it. The word pram is etymologically a shortening of its now less
