Honorary members

Olf Broenink

Mister Broenink helped with the automation of the membership records of W.S.G. Abacus. Moreover, he has been part of the auditing committee for ten years. Furthermore, he became a honorary member by giving a lot of good advice. Mister Broenink has said goodbye to the university in 2003.

Michel ten Bulte

Michel ten Bulte

Michel ten Bulte was not only a board member as a student for two years, but fourteen years later, he was a General Adjunct for two years. Besides smaller activism he was involved as an employee in TW for many years and he meant a lot for the students. Mister ten Bulte is still walking around in the Zilverling and is a welcome guest in many Abacus activities. For most board members, Michel ten Bulte is the first person to go to if you need something done in the Zilverling.

Henk Cammaert

Henk Cammaert

With four years of General Adjunct in the board of W.S.G. Abacus, mister Cammaert meant a lot to Abacus. He always had a good financial say in the matter at the department of mathematics, which had done good to many drinks and activities. He also maintained the contact between the students and the staff. Nowadays, mister Cammaert is retired but mathematics will always be in his blood.

Jaap Doosje

During his student time in Enschede, mister Doosje was in the board for three years. To finance his studies, he was a swimming teacher. Now, he has swapped his job for his current job as a math teacher. After his board years, mister Doosje organized a trip abroad for Abacus.

Piet le Grand

Piet le Grand

It is easy to support an association if it goes well, but it gets harder if things go wrong. When, right before a GMA, there was no financial year report, mister le Grand sacrificed himself as a auditing committee member to put this together. This process was repeated for a number of years. Also, Piet le Grand was a committee member of the Ideaal!-committee for over ten years.

Trudie Hondelink

Trudie Hondelink

As an employee of the cafeteria, mrs. Hondelink provided the drinks, parents’ days, open days and symposia in the former TWRC-building (now the Cubicus). Often she was the stabilizing factor fo the people who had little or no experience with organizing things. After she retired from the TWRC-building, she moved to the Spiegel. Nowadays, she is working at “Boerderij Bosch”. According to the other honorary members, Trudie was the ‘mother’ of TW.

Erjen Lefeber

Erjen Lefeber

The continuation of a committee is easy because you have a lot of predecessors to fall back on. The establishment of a committee ‘from scratch’ is obviously a lot harder. Mister Lefeber encountered this when he started the CoCo in 1993. In addition to this, Erjen Lefeber has done numerous committees, including the symposium committee and he has been vice chairman of the board of 1993-1994. After graduating, he still remained involved in Abacus and has provided a lot of support behind the scenes. The last committee he has done was ‘Geras’, the lustrumcommittee in 1999. He now works as Asisstent Professor at the Faculty of Mechanical Engineering in Eindhoven.

Frits van Beckum

Frits van Beckum

Frits van Beckum has always been very involved in the contacts of TW with ITB (Institute Technology Bandung). He can be found regularly in Indonesia to maintain his contacts. Mister van Beckum was a popular man in TW and he always sang beautifully in his deep voice. Sometimes he sang in “barbersjopjes” if we had a music evening or party within TW (this was often with Stephan van Gils and Brigit Geveling and a fourth person – who changed quite often).

Diana Dalenoord

Diana Dalenoord

Diana was a member of the editorial board of the faculty magazine the TW10 and later on the Ideaal!. She also was the bridge between Abacus and the employees of the department of Applied Mathematics. Through her it became possible to involve the employees in different activities. She was not only the bridge between students and employees, but also for the alumni. If there was need for a speaker for a symposium, Diana could always find someone. Diana has been very involved in the Twentse Wiskunde Estafette, an event that Abacus and the study AM still organise together. Diana has meant a lot in the organisation, they arranged a lot and took care of the contact with the schools. Finally, Diana always had a sympathetic ear for the students and you could discuss anything with her.

Even now, Diana means a lot to Abacus. She regularly write pieces for the Ideaal! and she is still invovled in Abacus activities such as the Sinterklaas activity, the introduction barbeque and activities such as a lunch lecture or Mathematical Café, where she also provides speakers. All in all, Diana is a very active member and is committed fully to Abacus and TW for over 25 years.

Brigit Geveling

Brigit Geveling

Mrs. Geveling has been active for Abacus for twenty-five years. She has been General Adjunct in three consecutive boards. Aside from organising various small-scaled activities, she also organised several activities during multiple lustra and she realised several well-received cultural evenings in collaboration with Abacus.
During her years as bachelor coordinator of the study programme, she was not only important for the students, but also for Abacus. Several times, she changed the timetables of the Bachelor programme at the request of board members, to make sure the students could attend sports days, symposia or other activities. Mrs. Geveling was also the first person who was willing to think along and to assist when something had to be arranged.
