the time of John W. Carter's death, his son, Richard B. Carter was still studying at Harvard, but after his graduation in 1898, he joined the company. After a period of learning the business, he became its head in 1903. Under Richard Carter's leadership the company outgrew its Boston location. In 1909 a new factory was built in Cambridge and occupied in 1910. The building's huge "Carter's Inks" electric sign faced the Charles River and was an area landmark for many years. Richard Carter continued his father's commitment to research and development of inks, glues and related products. In the mid-1920s, when upmarket fountain pens were a popular luxury item, Carter began its own range of pens, more specifically in 1926. The line was discontinued in the early 1930s, but they are still fondly remembered and sought after by collectors. Carter's also manufactured mechanical pencils, as well as desk pen sets. Samuel D. Wonders was elected president of the company in 1949 and served until 1955. Francis J. Honn invented the highlighting marker (under the trademark Hi-Liter) as the Vice President of Technology at Carter's in 1963. In 1975 the company was sold to Dennison Manufacturing Company, now Avery Dennison. Samuel D. Wonders was followed by Nathan C. Hubley, Jr who retired as president in 1976 when the company was sold to Dennison. To help with the transition, he remained with Dennison as vice president until 1977. Post acquisition After acquiring Carter's Ink Company in 1975, Dennison made the business decision to discard all of Carter's records from the 1860s on, including all of Carter's meticulous ink research records. The Carter name is still used by Avery-Dennison on some ink-related products such as rubber stamps. The Carter's Ink building in Cambridge still stands but has been adapted to other uses. In the summer of 1984, the Thinking Machines Corporation (the market leader in parallel computing by then) moved its headquarters to top floors in the building. Five years later, TMC signed a ten-year lease with the building, for US$6 million a year. In 2004, the building was converted to include 130,000 square feet of lab space to accommodate acquisition by ViaCell, a cellular medicine research company later acquired by PerkinElmer. Nowadays, the former Carter's building is occupied by The Forsyth Institute, one of the leading centers for dental and craniofacial research in the world and affiliated to the Harvard School
